Spy Photo of my car...(long)

...track testing at Texas World Speedway this past weekend. New mods that were tested:

- Abt A8, 17x8, ET35, 5/112 alloy wheels
- Sumitomo HTRZ-II tires, 245/40-17 (front)
- Bridgestone Potenza S-02 PP, 245/40-17 (rear)
- Porsche/Brembo 993tt calipers
- Audi Euro-S8 rotors, 323x30
- Kerr Friction racing brake pads
- Tilton Brake Proportioning Valve

- RS2 front bumper cover (well, the only test was that it stayed on the car!)

Previous mods:

- Abt sport springs
- BOGE Turbo Gas shocks
- Delrin suspension bushings

Observations:

The car behaved very well. I was very happy with all of the modifications. Despite some serious body roll that remains (still no rear swaybar), the car handles very well. Even without the rear swaybar, the car is very neutral through corners. The track was wet for some of the weekend and at least three times I went through one particular corner and with a steady steering input, got my rear tires to slide out a bit. By no means does this car plow like most Audis that I have driven.

Braking was very good. The brakes were easily able to lock the front tires at somewhere around 90-100 mph, even with the brake bias set fully to the rear. Unfortunately, the brakes aren't completely sorted out a) because of the pathetic rear brakes that Audi fit to the CQ, and b) because my ABS isn't working properly. If I can get more braking in the rear, I won't mind running without ABS, but in this condition, the fronts were locking too easily. I am leaving way too much braking power on the table to make me happy. I also was running my tire pressures too high for most of the weekend, which didn't help. Still, nobody that I followed all weekend was able to outbrake me in the infield (though much of that is driver confidence). Kerr Friction racing brake pads remain my personally endorsed favorite pad, period.

The Sumitomo HTRZ-II is a very good tire. It gave good, predictable traction. As far as I can tell, it is also wearing very well.

Conclusion:

Despite driving well all weekend and being very happy with the car, I was one second off of my best time that I achieved with none of the above mods (except suspension) and 205/60-15 AVS Intermediate tires! What? Well, because of the way that TWS is designed, I knew that the brakes wouldn't make a huge difference in lap times. However, I was hoping the extra traction from larger, stickier, and lower profile tires would help. The tires certainly felt better that the stock sized tires, but they didn't seem to make that much difference. I think what happened is that the effects of the tires, were negated by the negative consequences of heaving a huge amount of rotational mass on my car, in the form of heavier wheels, tires, and brake rotors. Basically, I made my slow car slower and the additional grip wasn't enough to make up for it. This is something important for you guys with stock motors to think about.

Speaking of that, this track event was the last thing that I was waiting for before putting my car under the knife for its 20V turbo conversion. I will keep you informed as I make some progress. If any better photos of the car show up, I'll post them.

Later,

With a set of coils you can get high spring rates to where you dont need anti-sway bars! ;o)

The red & black look sharp!

Hey Jimmy, that RS2 bumper is gonna look good when painted. Is it the real thing? Who did you score it from?
Just curious.

...but I totally agree with your philosophy - swaybars are a compromised solution. However, I already have the swaybar, so I still may give it a shot to see if I like it. Brandon Hull says it made a night-and-day difference with his car.

Anyway, the motor conversion will take priority now and I will sort out the suspension afterwards. Almost for sure, I will go with a C/O program, though.

Yeah, the red and black looks kinda tough, especially for a track car. Thanks, Mike.

...but the space between the tire and the front control arm is pretty tight. An inch (a cm?) is as good as a mile. The rears are way no problem.

This is on a lowered car, no rolled fenders.

YMMV!
