That’s what the fastest Vette in my class beat me by. My goal in life is to be faster than those guys.

I already posted this video, but for reference, here it is again. The lap timer was lagging for some reason, but you get the idea.

My LSD is completely shot. I’m losing tons of time out of right handers. I have to manage the right rear wheel spin until the wheel is damn near straight then I can get on the gas. I’d be willing to bet I’m loosing a full 2-3 seconds just from that alone. Then there are the brakes. I have to be very careful and can’t get on them hard because of axle hop. Once I install the bias controller, I’ll be able to get on the brakes much harder and sooner after jumping off the gas. I’m thinking maybe another full second a lap there.

So with those two things, that’s already 3-4 seconds. What’s cool is I’m under power and over weight and even then, I’ll be in the upper 1:40’s. That’s a very respectable time. Even right now, people were surprised that I’m in the low 1:50’s.

More power will come when I swap an LS1 along with 120lbs of lightness between engine and transmission and UMI crossmember.

What are your thoughts on Lexan rear glass? Worth the price?

I’m also thinking about stepping up to 18’s and running a 295 tire, the widest NT01. Maybe someday they’ll make a 315.

I’ve read a lot about Shocks. Mine are adjustable Koni fronts and Sams revalved rears. I’m thinking UMI’s shock package would probably help, but I’m not sure.

What else?

Front aero?

Remember the car needs to stay street legal.

With the brake bias fixed and a working LSD, I would have been faster than the majority of the cars there. That’s pretty exciting. With some more work, it’ll be track monster.

Thanks guys!

Wow! We usually get about 60 laps out of our A6’s, but we’re pushing it on really aggressive concrete. IFF we get more than a year before they’re Levi’s, they get replaced because the VOCs are boiled out and you can’t rely on them run-to-run.

But tires are everything. Spend your budget there, upgrade elsewhere as budget allows.

You are still using A6s or is that a typo? The A7 stays fast much, much longer than the A6 does. They both have the same compound but the construction changed significantly.
