Interesting. Want to make me a set? Call it a fee for delivering your wheels :-)

Yeah I'd do it - the second time around will always end up being better too

I used the 3/4" bearing (1-7/16" cup) with spacers to accept the 12mm Penske stud - from the looks of my Bilsteins - it would they appear to have the same 12mm stud.


A friend made me 3/4" - 12mm spacers that I pressed into the bearing, but I also picked up some hard plastic 3/4 - 1/2 spacers from McMaster that will also work for those that don't have access to a lathe (can see them in the pics below).

...snip...

Installed with rubber sealing washer and safety washer

Nice DIY top hats! Did you cut more threads on the Penske extender? Did you have to cut off the extender to avoid hitting the hood or allow the spare tire to fit in the trunk?

It looks like you gained some shock travel as well (like Jim R did)?

I didn't have to cut any more threads. No problems with the hood - the angle of the picture makes it worse than it really is.

Well I got added bump travel but not like Jim did. Jim isn't using the Penske upper spring retainers - I am - so that controls my bump travel, moving the Penske perch higher doesn't gain me any travel - now I did have to raise the lower spring perch to get back to my original ride height so I did gain some bump travel because I "raised" the car with the spring perch, but effectively lowered it with the top hats.

Any top finishers in the SD Tour (Driving S2000's) want to share some setup info?
What all have you done to your cars? Basically, does it take a reflash/vafc, header, intake, exhaust, coilovers, 9"wide wheels w/255's, and a wing to win?

Or, are you just bustin skulls with just coilovers and driving ability. What I'm trying to get it at is... were the cars that hit the podium fully / or close to fully prepped? Or, no?

Also, are any of you planning on attending the Wendover, UT Pro / Tour? I'd love some serious competition!

Power has very little to do with it. The money is best spent on decent shocks, a swaybar, choosing the right springs and an alignment.

Basically no power adders and just suspension mods. No wing.


The MX-5's were much closer to fully prepped than either of the Honda's in the trophies - albeit none of them are close to what most consider "prepped"
Interesting. Thanks for the response. I realize he's posted his "Setup.." however, things change real quick depending on surfaces, etc. I.e. Camber, toe, suspension adjustability, etc.

Thanks!

The photo below shows the closest I came to swapping ends on my second run on day two of the San Diego Tour. I got behind on the turn just before the turn into the finish and hit the inside cone. The car was more loose than I had experienced so far. I attribute part of that to the higher speeds and significant elevation changes with lots of off camber turns. But what about the car is causing this?

What makes a back end loose? I have a FSB at 200% of stock stiffness. The tire pressures for Dunlops were in the ball park of what others were running. The rear camber is at -2 deg. The rear toe is at -1/8" total. The shock travel in the rear is minimal. The rear springs are 600 lb/in. The rear bar was disconnected and it just provided a slightly higher speed at which the car still felt loose.

The two things I have come up with are to increase the rear toe and increase rear travel in case it's the bump stops (likely). I plan to try -1/4" total rear toe. As for rear travel I will try raising the rear ride height to start. Long term I will have to get shorter shock bodies ($330) or build new rear top hats like Jim Reyenga's or Nick's.

One more thing would be a large rear wing for higher speeds.

Any other ideas?

Everyone was loose on San Diego's surface. Our car was looser than it's ever been before.

As an aside, I was working the hairpin turn, and either you or your codriver was hanging himself on Sunday by downshifting to first when there was only a fraction of a second's acceleration possible before shifting up (unless you drew it out by busting the tail out, which happened more than once).
