Everyone knows I enjoy driving slow cars, spending stupid money on them, second guessing myself, and struggle making decisions on what I want to do. So, I thought I'd make a thread on current classes that are popular. I'm hoping this will make people like me or new students who don't know about racing and wondering what cars to buy can make a decent decision on what cars to purchase. Disclaimer I'm still a noob so bear with me. I also don't know what I want to do in TT/Racing area. The class popularity can change by event/over a season drastically if cars break, people run dry on money, etc...
Basic Cost To Go Racing (W2W safety gear cost, common wear items, most expensive items constantly needing to be replaced, etc...):
This section will include basic things and give a range of cost with example of specific cost from personal experience. Please add more to the list if deemed necessary.
NASA Required Safety Gear for W2W:
Optional but highly recommended safety gear:
Time Trial is a popular option with very few restrictions on what type of cars can be out and competing. As such, safety requirements are that of HPDE. It's easy to have some really shitty safety setups as a result. So then, a few TT and HPDE safety thoughts:
Common wear items:
Recommended season maintenance or things to look out for:
These will not 100% work for everyone. Some cars will run hotter. Some cars will burn more fluid or overheat fluid. Some cars will need to be less maintained. Just pay attention to the fluids, read online forums of when people do maintenance and replace when necessary. This maintenance guide will also help you spot possible problematic issues that could save you and your car from a big wreck or major break down.
As a generic statement, the faster you go the more expensive it is. This is usually the case 90% of the time but doesn't mean that's always the case. For example, HC is usually less expensive to buy into than let's say GTS3. e36 GTS cars can go from 20k-40k range right now. e46 GTS cars are looking 50-70k. While you can pick up a HC2 car for 7k-12k.
Basic Classing Overview:
Time Trials - (TT):
NASA Time Trial (NASA TT) is an automobile road course competition series focused on time
trial style competition. This is not W2W racing so it's not a competition of who finishes first after a race period of time but who has the fastest lap time after a time period (~15 minutes). Driving in TT requires a license which is approved by the regional TT director:
1) Successfully completing a NASA HPDE 4 event, or current NASA Competition or
Provisional Race License, or current Competition Race or TT license with various other
organizations at the discretion of the TT Director, or an extensive verifiable driver history of
open passing road course events or competitions with other reputable organizations (may include
former racers without a current competition license, etc.) at the discretion of the TT Director and
run group leader.
2) Exhibiting knowledge of the NASA TT rules, and understanding of the consequences of noncompliance.
3) Exhibiting understanding of the nature of NASA TT including the spirit of cooperation that is
required between drivers on the track, and the high standard of driving performance and safety
that is expected.
4) Exhibiting knowledge of the technical and safety inspection process
There are a total of nine NASA TT competition classes. The classes are: TTU (unlimited); TT1, TT2, TT3, TT4 (based on Adjusted Wt/Hp Ratio); and TTC, TTD, TTE, TTF (based on Base classing and Modification Points). In addition, there are two classes (G & H) that are listed for purposes of base classing only (TTC-TTF competition vehicles only). There will be no competition in either TTG or TTH.
The classing rules for TT vehicles mirror those for the Super Touring/Super Unlimited and Performance Touring race cars. So, any car legal for a ST/SU or PT race class will also be legal in the corresponding TT class. The classes “map” to each other as follows:
Based on last seasons results. Typical cars that usually run in TT classing at Mid-Atlantic are below.
TTF:
TTE:
TTD:
TTC:
TT4:
TT3:

TT1:
TTU:
Wheel to Wheel - (W2W):
Your first step to racing is acquiring your provisional license. It has similar requirements to getting you TT license but with a little more depth. After your provisional you will move to your competition license if you stick with a clean record for 3 race days? So, two weekends worth of racing I believe?
13.1 Issuance of a NASA Provisional License

Factory Five Racing Kit Car Eligibility
The term “eligible model” is used throughout this publication in context only. This is a kit-car or a “home-built” car. Therefore, a “finished car,” built according to the Factory Five instructions, these series rules, and other applicable NASA rules, is considered an “eligible model” for the series. This model shall be known as Factory Five Challenge Series Racer. (FFR part #5003)
Ford Mustang ‘Donor’ Car Eligibility
Parts from a “donor” car are required to assemble the finished race car. The term “eligible model,” found within this publication in the context of references to any parts or assemblies that is (or was) found on the donor car, should be considered a reference to the 1987 through 1993 Fox bodied Ford Mustang model with the Ford 5.0 liter (302 cubic inch) high-output 225 horsepower (factory rating) engine, unless otherwise specified.

If you would like to know about where your car is placed or what classes have what cars you will want to go to the NASA - RULES site
Basic Cost To Go Racing (W2W safety gear cost, common wear items, most expensive items constantly needing to be replaced, etc...):
This section will include basic things and give a range of cost with example of specific cost from personal experience. Please add more to the list if deemed necessary.
NASA Required Safety Gear for W2W:
- Full cage (see NASA CCR for current requirements) - I (Ryan) would recommend adding footwell protection by the pedals. It's a spot a lot of people I feel like miss after working tech for a bit. Cost: ~$5,000?
- Fire-resistant racing suit, Recommended SFI 3.2/A5 or FIA 8856-2000 Cost: $400-2500
- SA-rated helmet, Cost: $180-2000
- HANS (other head & neck restraints may be approved, check CCR), Cost: $500-1000
- Balaclava under helmet, Cost: ~$70
- Gloves, Cost: $80-200
- Nomex socks, Cost: $20-70
- Fire-resistant shoes, Cost: $100-400
- 5+ point harness with recent manufacture date (for exact age, see CCR), Cost: $180-400
- Fun fact - a racing seat is not technically required although you should have one. Get a halo seat. Any racing seat has to be within specs (again, see the CCR) although some that are out of spec can have a back brace added. Halo Seat Cost: $1000-2000, Non-Halo Seat Cost: $500-1500
- Center net is required if you do not have a halo seat, Cost: $100-150
- Window net, Cost: $50-100
- Fire extinguisher OR fire system, Cost: $500 or $2000?
- Electrical kill switch, DIY Cost: $100-200?, Shop Cost: $500?
Optional but highly recommended safety gear:
Time Trial is a popular option with very few restrictions on what type of cars can be out and competing. As such, safety requirements are that of HPDE. It's easy to have some really shitty safety setups as a result. So then, a few TT and HPDE safety thoughts:
- This shit is a system. Do it right.
- Either leave your interior 100% stock with factory items (seats, 3-point seatbelts, airbags) or do a "basic" safety package
- "Basic" means seats (expired is OK), 5/6 point harnesses (again, expired is OK), and a roll bar. No harness bars.
- Make sure the holes in the seat back are at the right height for your shoulders, to allow a safe angle for the shoulder harnesses to approach. Check the NASA CCR for some good pictures/guidelines (Schroth has a good set as well if you Google)
- Racing seats mean you need to have side/bottom mounts and floor mounts for your car. Consider that cost.
- Whatever safety setup you have on the driver's side should be mirrored on the passenger side. Don't get your side all safety'd up and leave the passenger side stock. That's a great way to never get an instructor in your car.
- A lot of this can be picked up (relatively) cheap as expired items that racers have to upgrade every few years.
Common wear items:
- Brake pads and rotors, some cars eat pads and rotors faster than others
- Tires, if you want to be really competitive or have a lot of money you will be replacing race tires every couple of weekends
Recommended season maintenance or things to look out for:
These will not 100% work for everyone. Some cars will run hotter. Some cars will burn more fluid or overheat fluid. Some cars will need to be less maintained. Just pay attention to the fluids, read online forums of when people do maintenance and replace when necessary. This maintenance guide will also help you spot possible problematic issues that could save you and your car from a big wreck or major break down.
- Replace differential/transmission/cooling fluid at least once a season
- Replace oil and filter at least twice a season
- Bleed brakes at least twice a season
- Flush brake fluid once a season
- Check brake lines when doing brakes or changing wheels/tires
- Flush radiator water once a season (yes just water, do not run anti-freeze on a TT or race car)
- Inspect all other fluids (power steering, etc...) at least twice a season for wear
- Check torque on commonly removed bolts to ensure everything is tight
- Check oil level at least once a track day, it will help spot engine problems in advance
As a generic statement, the faster you go the more expensive it is. This is usually the case 90% of the time but doesn't mean that's always the case. For example, HC is usually less expensive to buy into than let's say GTS3. e36 GTS cars can go from 20k-40k range right now. e46 GTS cars are looking 50-70k. While you can pick up a HC2 car for 7k-12k.
Basic Classing Overview:
Time Trials - (TT):
NASA Time Trial (NASA TT) is an automobile road course competition series focused on time
trial style competition. This is not W2W racing so it's not a competition of who finishes first after a race period of time but who has the fastest lap time after a time period (~15 minutes). Driving in TT requires a license which is approved by the regional TT director:
1) Successfully completing a NASA HPDE 4 event, or current NASA Competition or
Provisional Race License, or current Competition Race or TT license with various other
organizations at the discretion of the TT Director, or an extensive verifiable driver history of
open passing road course events or competitions with other reputable organizations (may include
former racers without a current competition license, etc.) at the discretion of the TT Director and
run group leader.
2) Exhibiting knowledge of the NASA TT rules, and understanding of the consequences of noncompliance.
3) Exhibiting understanding of the nature of NASA TT including the spirit of cooperation that is
required between drivers on the track, and the high standard of driving performance and safety
that is expected.
4) Exhibiting knowledge of the technical and safety inspection process
There are a total of nine NASA TT competition classes. The classes are: TTU (unlimited); TT1, TT2, TT3, TT4 (based on Adjusted Wt/Hp Ratio); and TTC, TTD, TTE, TTF (based on Base classing and Modification Points). In addition, there are two classes (G & H) that are listed for purposes of base classing only (TTC-TTF competition vehicles only). There will be no competition in either TTG or TTH.
The classing rules for TT vehicles mirror those for the Super Touring/Super Unlimited and Performance Touring race cars. So, any car legal for a ST/SU or PT race class will also be legal in the corresponding TT class. The classes “map” to each other as follows:
- TTU = Super Unlimited
- TT1= ST1, “Adjusted Wt/HP Ratio” equal to, or greater than, 6.00:1
- TT2= ST2, “Adjusted Wt/HP Ratio” equal to, or greater than, 8.00:1
- TT3= ST3, “Adjusted Wt/HP Ratio” equal to, or greater than, 10.00:1
- TT4 = ST4, “Adjusted Wt/HP Ratio” equal to, or greater than, 12.00:1
- TTC = PTC
- TTD = PTD
- TTE = PTE
- TTF = PTF
Based on last seasons results. Typical cars that usually run in TT classing at Mid-Atlantic are below.
TTF:
- NA 1.6L Miata
- BMW E36 318, 323, 325
- Most any N/A FWD econobox (Sentra, Mazda3, Civic, Integra, etc...)
TTE:
- NA/NB Miata
- BMW E36 except M3, E30 all
- Acura/Honda Integra, Civic, etc...

The term “eligible model,” found within this publication in the context of references to any parts or assemblies that is (or was) found on the donor car, should be considered a reference to the 1987 through 1993 Fox bodied Ford Mustang model with the Ford 5.0 liter (302 cubic inch) high-output 225 horsepower (factory rating) engine, unless otherwise specified.
