I was all set to start building up my Z for f-stock competition. I'm getting a 35mm bar (haven't quite decided hollow or solid yet) and Koni DA all around. Arleady have the Borla and will have the front end realigned shortly.

Then I came across 1LE.net, and I'm wondering which is better, do a 1LE conversion (I'd get a 36mm bar) or stick with the original plan, up above? I'm staying in Stock class and this is my summer daily driver.

 

First off, you don't need DA's. I'd much sooner see you/recommend SA's. Second, your lid has to go away to run FS legally. Third, having run both 1LE and non 1LE cars a lot, it might help you to know that I ordered my 2001 Z28 specifically to autox. 1LE wasn't available in '01, and I didn't care. I think a Z28 with a big bar is a more consistant autox car than a 1LE.

Why? Well, I always wished I could make the rear of a 1LE softer for autox, but you can't change the rear springs. So, I got the idea to try and stiffen the front wheel rate of a Z28 toward that of a 1LE, leaving me with what I wanted.

Since 1993 when the 4th gen came out, ONE 1LE 4th gen has won Nationals. All the other 4th gen wins were in non-1LE cars. 1998, 1999, 2000, 2003 were all won "regular" Z28's. I setup, or helped on the 98, 99, and '03 cars (by the way, the 99/03 winner is a '95 T-top car). I also won a ProSolo Championship in 2002 with my car, and I lent it to a friend who finished 2nd at Nationals that year in it (I ran ESP), making it the fastest 4th gen that year.

 

Thanks for the advice. That's actually what my wallet was hoping you'd say. I didn't know the 1LE was so rare a winner in auto-x.

I already swap lids with the stocker for auto-x (probably should've mentioned it).

Interesting point on the SA. I will consider that route much more (your track record carries alo tof weight).

Thanks.

 

Sway bar material also makes a difference. I think the 1le is carbon steel, but other aftermarket ones, like the BMR is chromoly. Which is alot stiffer. Just something to look at.

 

Ahh...the plot thickens.

Thanks for the advice. I plan call Sam Strano pretty soon, people say he'll talk to ya one on one to get the right set up you want/need.

 

By all means call Sam. He's at the Pro Tour in Peru this weekend so give him until next week.

 

This is not right. Chromoly steel alloys are substantially stronger (higher yeild and ultimate strength) but not substantially stiffer that plain carbon steel.

All steel alloys have about the same stiffness (modulus of elasticity) but can have very different yield strengths and ultimate strengths.

 

Man!!! Talkin' about dredging up an old post!!!!

 

Well, either way, adjustable shocks are only allowed if they have 2 settings.

Read the rules.

 

Rules for what class?
