What issues are you trying to improve with a new pump and box ?

The Maier Racing built suspension has a tremendous amount of adjustability. The uprights are amazing and every angle you can think of can be adjusted. Basically, we made a significant spring rate change, sway bar, and geometry change and the turn in is incredible. In the next month, more testing is needed to finalize the settings. I should be dailed in for RTTC III.

The steering pump and box are being upgraded for a better feel and reliability. I had changed ratios late summer with a cheap box and it failed on me right after OUSCI and the November Goodguys. The new box is the 600 series and the pump is set to match my car.

That's a mean looking car man! Love it!

I was very fortunate to have amazing people work on the car to get it were it is at today. Thank you to: Maier Racing, JRI Shocks, Wilwood Brakes, K&N, Mast Motorsports, DPE Wheels, Cort with Seever and Sons, The Rear End Shop, Elite Auto Films, Elite Auto Glass, Car West Elite, PPG, Kent Automotive, my buddy Rob who did all the electircal, and of course my Dad.

We made some geometry changes to the front suspension a few weeks ago that made a huge improvement. I ran the car a couple weeks ago and I was very pleased with results. We are in the process of upgrading the steering components with a pump and box from Turn One. We also adjusted the corner weights again and the balance seems good. With the Michelins, the car weighs 3230. The larger wheels and heavier tires are about 100 lbs more than the CCW's and Hoosiers.

I hope to see a lot of you guys here on the forum at RTTC III. It should be a great time.

Here are some shots from OUSCI where I finished 3rd.

You're car looks Sitcky...

I was texting Dave after your second AutoX run @ Optima (in the freezing cold). Going off memory, I think I wrote - I don't see anyone beating Brian!!'

Great job Sir...

Great gathering of wicked track cars !

Just curious Brian what is the backspacing and hub bore on your DPE wheels, and how much were they if you don't mind me asking I'm wanting to pick up a set of their super concaves for my 2nd gen?

Thanks

Not cheap, over $1200 per wheel. His backspacing would only really work if you had the exact same steering/suspension as him.

Cant wait to see your car on TV Brian, should make for a good show

Thanks Slo_Z28, I figured it was about 6k for a set I was trying to pin an exact number! lol

Nice Add on the backside of the HotRod Cover .
How much camber were you running in the pick ? looks like a ton from that angle .Any chance you shortened the upper A arm and took some -camber out ? Just guessing here .

The backspacing I use is simular as the rear on a C6 Z06. I use that on all four corners. The rear wheels are 13" wide and 9.25" back space. The fronts are 11.5" wide 8.5" back space. The wheels will be priced dependant on size and color choice. Mine are special made wheels that on not on the website. DPE does a great job with their wheels and and come up with many setups. $1200 per wheel is about average. Mine might be a bit more than that.

Cort, with Seever and Sons, is the man to talk to in Nor Cal if you need wheels. (925)463-3443
