My car classification...

[Jet Jockey]

Hi folks,

Would just like some help to make sure my car meets all the requirements. It started life as a 2004 Audi B6 A4 Quattro with a 1.8T motor.

After reading the rules it is my understanding my car falls in the following class;

PREPARED B (P/B)

"Generally all 5 and 6 cylinder normally aspirated and 4 cylinder forced induction (Audi's 1.8 turbo) cars prepared to Prepared rules..."

On the safety side I meet all requirements but I'm not sure about the B statement and how it relates to E - 3 which states they are not required if indeed they are the same thing. Going further and playing the Devil's advocate why would a window safety net be required in a conventional car and not a topless car or since a roll cage is not even required for this class how would one secure a window safety net without a roll cage?

For the record, I do not have a window safety net and I hope it is not required. I just don't see how with my seating position in the car (far back) with a 6 point safety harness this would be a problem.

1. SAFETY

B. A window safety net must be installed to prevent the driver's arms and/or head from protruding through the window
opening, unless the car is topless. Window nets or arm restraints are required.

E. The following items are highly recommended but not required:

1. Fuel cells
2. Racing tires
3. Window safety clips and straps
4. Master switches (kill switches)
5. Scattershields
6. Oil catch cans
7. Fire extinguisher, if securely mounted

Thanks,

Mike

What disqualifies your car from SPB?

What disqualifies your car from SPB?

#3 head lights... I removed the stock Xenon headlights, replaced them by a gutted halogen casing modified with only LEDs to be used as day time running lights only. This saved 10 lbs between the two headlights.

#7 Sub frames... Everything was remove and custom made steel and aluminium ones were designed and manufactured.

#9 Fenders... The OEM front and rear fenders were cut, Carbon Fibre extensions are going to be made so as to run much wider wheels and tires.

Arm restraints can be used in place of window nets. The restraints are inexpensive and easy to get used to. Yes,cutting of the stock fenders lands you in Prepared.(B) Welcome to the group!

Thanks for the info.

I assume the sub frame mods would have also landed me in the same class?

Maybe I missed it but what are the rules when it comes to side windows. What I mean is, does the driver's window need to be open when on the track? I assume the same rule applies if there is someone in the passenger seat?

What if the car is built with bolted on Lexan windows is that allowed?

[breakaway500]

Drivers and passenger front windows must be down while on track.Permanent closed windows in these locations would not be allowed,I am pretty sure,as you could not point by, and you would be in violation of the windows down rule.Lexan replacement windows are allowed in prepared. You should post up a picture of this red rocket!

Window nets cannot be attached to an open car so arm restraints are used.
You can use arm restraints instead of a window net in a closed car.

In PB you will need a roll bar and a fire suit, gloves etc.
If you are a student, all safety gear, seats etc should be the same for the instructor in the passenger seat as the driver.

That was then...

From fall 2005 at the Audi event at LCMT... Coming out of Namerow corner. The car was my DD with its full interior. The suspension and brakes were already upgraded and so was the motor with a MTM K04 kit putting down 210 WHP on a Dynapack (stock was 126 WHP).




This is now...

The mechanicals are almost done but still need some tweaking. The body still needs some work mainly the CF fender flares to allow more room for the wider wheels and tires and some paint to clean it all up. The wired mesh grills need to be reinstalled too.

I know, I know, it’s not pretty with the cut out fenders but it will be fixed with CF extensions by spring time. This was taken at VIR a couple of weeks ago during the mechanical shake down. Sorry for the quality of the pictures. CF hood with all the weight removal done paid off. We could go a little deeper into the weight cutting but since I’m not racing to make money all things need to come to a stop at one point. In any case with all liquids onboard, full fuel, safety harness and all safety equipment it weighed in at 2843 lbs and with the new found power it’s quick (enough for me anyway). Even in this picture you can tell that the fenders needed to be cut. Theses are my 17 inch wheels I plan to run just for lapping. At this time they are mounted with some Toyo RA1s in a 235/40 size with 15mm wheel spacers. For competition I have a set of Volks TE37s with an aggressive offset of 22mm shod with some Hoosiers in a 285/30 size which definitely did not fit under the stock fenders.




Another angle. Holly wheel gap Batman! This car belongs on an off road track. We will fix this problem over the winter months. Personally I think the shop cut the rear fenders too much at four inches where as the fronts were only cut down two inches (for now). Test fitting the Volks with the Hoosiers will let us know if the front fenders need more cutting.




A much more powerful motor was built by Justice Racing Engines (now a 2.0L) and the tuning was done on their engine dyno by Franz Diebold of Diebold Autosport.

OK thanks again for the info. I may then install a window net over the winter months.

Since it will be my first time with your club I will need one of your instructors to ride with me to check me out.

Questions:

I don't intent on having a passenger seat in the car at least not when competing (+25 lbs) but I have an old spare race seat (Sparco Pro 2000) that can be installed fairly easily in probably 15 minutes. Would that seat satisfy your club for a check out ride?

My harnesses are non FIA approved for that seat, does that prove to be a problem for a check out ride?

Finally would I require a window net on the right side for the instructor for the check out ride?

Perhaps it would be simpler to borrow a friend's car for a check out ride.

As for a roll bar well I have a roll cage. It was inspected and certified by the local FIA person in the Montreal area. My only regret about it was I was not fully committed at the start of the roll cage project to make it a “full” cage with it going through the front firewalls all the way to the front suspension attachment points. However the rear was structured to the rear suspension points. The roll cage was welded in several points to the car’s chassis.




Thanks,

Mike

Car looks good! You are going to have to install hood pins on that CF hood to run with COM. (it's a rule) Try the arm restraints.They are cheap($30 pair) and much easier than mounting nets.(zero effort vs. lots of effort) Otherwise,yes,nets on both windows.Your harnesses will have to be up to date on both the drivers and passengers set to run with COM.

OK I guess I'll have to look for some arm restraints.

I'll see if I can get some "cheaper" harnesses for the right seat.

As for the hood pins they are already installed but they are the stealthy ones...

^Very cool!!

lovely! Keep in mind that in Prepared you can use slicks-- you do not require DOT tires. Slicks will be significantly faster-- for an experienced driver.

Yes I'll have to experiment with slicks at one point.

I looked at Michelin slicks (I have a friend that runs Porsches in racing) but the sizing in 18s wasn't good (not the right width but especially too tall).

Do you have any info on slicks you could pass along. What brand would you recommend?

Whatever the classification ends up being, the car seems like it is a total badass! I can't wait to see this thing out there.
