Default [C5Z06 A/X] Getting back to stock...

So I've run in a couple practice Solo2 events and I've decided that I like it enough to keep going and try to compete. Now that I've made that decision I started reading the rule book and realized that I need to get back to stock to be even close to competitive. I've listed the things I need in this thread.

Please take a look and see if there's anything in there that you guys have and you need to get rid of or if you see me making a mistake with anything there let me know.


Thanks,

Eric

Stainless steel brake lines are not allowed in stock class, BTW.

Have fun!

Thanks... I just went back and figured out where I messed that up...

I read this:
Substitution of clutch and brake hydraulic lines with solid metal or braided metal is allowed
But missed this:

on all cars manufactured before model year 1992.

You can also use 295/35ZR17 for front tires. In my experience, there is very little sidewall pinch, so you will end up with more contact patch.

Yup - 295's are the way to go up front. Also, get some Hawk HP+ pads, they are a fantastic autoX pad and even okay for HPDE occasionally.

I also noticed a big difference running Koni 3013 single-adjustable shocks, but that can be added later as you want to.

The Koni's would knock him out of stock class. He could get the 2004 Z06 shocks though. They are better than the 02's. Then he could sell his '02's to recoupe some of the cost.

SCCA Solo stock class rules allow the substitution of shock absorbers of a different make, as long as they are the same basic type and don't have more than two separate external dampening adjustments, so he can use non-adjustable shocks, single adjustables, or double adjustables. Unless I am missing something about that particular make of Koni (like if the fully extended length wasn't within +/- 1 inch of the stock shock) I don't see any reason it wouldn't be SS legal.

From the 08 Rulebook:

"13.5 SHOCK ABSORBERS

The make of shock absorbers may be substituted providing that
the number, type (e.g., tube, lever, etc.), system of attachment
and attachment points are not altered, except as noted below.
The interchange of gas and hydraulic shocks absorbers is permitted.
The following restrictions apply:

1. No more than two separate external shock damping adjustment
controls. This permits the use of shocks which originally
came with more than two external adjustments, which
have been converted to double-adjustables, only if the additional
adjustment controls have been permanently disabled
(e.g. via welding, epoxying, grinding off). Gas pressure
adjustment is not considered a damping adjustment..."

I stand corrected.

Now I need new shocks.

I want to be careful not to change too much at once - I won't know which change resulted in which improvement (if any). I think I need more seat time before I realize the value of these upgrades anyway. The real reason for tires is to keep from killing my street tires too early, the brake rotor change is to get back into stock qualifying condition, and the pads I figured I'd pick up now so that when the current ones go (and I'm sure that will be soon) I'll have them on hand to install...

I wasn't sure about the 295s... I was afraid that they wouldn't really fit well on a stock front rim and not rub (car is lowered on factory bolts, then aligned back to factory settings - I intend to change the alignment at some point).

taking the car in for a corner balance and a slightly more aggressive alignment will go along ways for you

Why not run ASP? You may be a little behind the curb, but you won't have to swap out as many parts (going back to stock)?

doje is right when it comes to NCCC prep rules, though; NCCC doesn't allow adjustable shocks in Group I.

I thought about it, but decided to start out in stock form for a while. When I can build a car that can compete in ASP I'll do it.
