Are your fenders pulled to fit the +45 wheels?

 

What are your spring rates and ride height (measured from center of wheel to fender edge)? That wheel's offset, combined with low ride heights and less negative camber reportedly results in fender rub issues. Glad to see yours are doing OK!

 

They are not pulled; only the inner lip is rolled nearly flat in agreement with STR rules. I really want to run at Packwood next year, and possibly Nationals, so I'm doing my best to stay legal, haha.

In the video you can slightly see where I got a little bit excited with the fender roller, and accidentally bent it outwards a little too much. It was only a very tiny portion. The fronts are VERY thin and need to be folded in very slowly. I had to push it back into place to get the outer contour flat again.

I'm using BC Racing coilovers at 10k/10k, with the OEM '05 FSB, and completely removed rear sway. I usually run with the shocks at full stiff all the way around, but occasionally dial the fronts down (softer) if it pushes too much. The car is very neutral with this setup on the squared tires.

My ride height is at 13.25" front, and 13.5" rear. Now that I think about it, I could just put my 255 rears on the front for fitment testing.

Here are some fitment pictures:

17x9 +45, 245/40F - 255/40R









...and going off topic, but I ran on a buddy's r-comps in exchange for letting him codrive at an event. These wheels had me a bit nervous, but they were fine all day!

18x9 +35 255/35 A6 on the rear. Can't remember front specs, but it was cloooose.

 

I myself much rather run proper offset-ed wheels and get a lower CG. 12.25" all the way around

wow 12.25?? thats pretty low. What size tire is that josh? 255/40 rs3?? It looks like you have a bunch of clearance underneath.

 

Yes 12.25", that "bunch of clearence" is a illusion due to the angle of the shot. The camera is sitting on the ground. The ground clearence is 3.25" from the ground to the jack points.

here's a couple more pictures showing how low it is, please excuse the dirtyness.


turning away from camera, looks to be about 2" of ground clearence when loaded up! haha

 

thanks for the info, i appreciate it.

 

No problem! Just note that it requires custom lenth shock bodies to run this low and not bottom them out over big bumps. At this height I still have probably 2.5" of shock travel. I was bottoming out my shocks last year in the rear and had to spend $$$$ to get shorter custom lenths bodies put on. I've seen a STR car that had the rear set at 12" but I think he might of moved it back up to 12.25" to avoid tire t metal contact risks.

One last pic, at 12.5" the A-arms are parrell with the ground. As you can see mine are alittle lower then that. Them JRZ 3 ways, ball bearing rear bar, and my rusty trailer bracket, gorgeous combo. HaHa Camera once again sitting on the ground.

 

anyone tried a 245/35ZR17 R1R on an ap1 to get better gearing?

-5lbs lighter per corner than a 255 direzza...

 

A few have, there are some posts about it if you search. The HART guys ran them on both S2000s, but switched soon after. daverx7 ran the R1R and preferred the RS3s. The general consensus is that the S2000 is too heavy for these tires, even the 255s. The R1Rs seem to do well on the MX5s though.
