Renshift, Springs Options

[Randal]

I totally blew my last two runs yesterday missing shifts.

I know part of this is the driver, but I also think the Rennshift springs are suspect.

When we first installed the Rennshift it took some getting used to, but it worked all the time. I've run 8 events now with the new shifter and it was fine for the first four, but not for the last four.

Saturday and Sunday at Alameda I was hitting reverse, shifting from first to second. Typically this was during cornering, but that is the way course work; you just can’t sit there on the rev. limiter waiting to the corner to complete.

Also during very heavy cornering (like in a slalom) shifting from second to third, it was going into fifth.

On down shifts from third to second it was hitting reverse. I destroyed a great run on Saturday on the second to the last corner....just couldn't find second. (Like Grind Me A POUND!) Very ugly.

So what are the ratings on the standard springs? Is there somewhere I send my existing springs to have them tested? What heaver springs are available?

At Alameda I was shifting up/down 8 times. Miss any shift and you blow the run.

BTW the 911 guys don't have to shift more than once.

It's funny - people are SO different when it comes to the springs.

Please come take a ride with me in an autox venue; you’ll find the lateral forces somewhat more powerful/heavy than what would be considered "normal."

Secondly, the springs worked fine for the first 4 events (8 or 10 runs per event), but then started to go off.

As Brad said everything on the car is solid as it was just in the shop being checked.

It could be that my new slicks (Hoosiers) were really hooking up (they were) thereby creating more cornering force and in turn a heaver hand by the driver. However, I discount this as I’m strapped in very tight in a Kirky seat that keeps you in one place..

BTW what is the spring rating on the old/ new springs? Seems like a big difference just compressing the old one, by hand, vs. the new, which is hardly compressible.

Should I be putting the little inter spring back in with the new ones I just got from Brad?
