Yes, particulary near the skirt, appears to be a bit more room in rear/bumper area. On my way to measure now....

I have a 18/305/35 also, but i did zero body modification with an offset of 33.

Yes, the 6766 Dual BB.

Jake could you please post a few more pics of your setup, preferably from the back to see how it fits under your bumper?

(here's a few more pics of 305's on InDiGlOM3 for reference)...

Btw, checked today locally and the 285/40's were only Nitto 555 not the R's so cancelled that as I need to order them which will take time...

Yeah, that's with a 10" rim. With an 11" rim as Jake's, things will be different.

Jake are you by any chance running 0 rear camber? Is that possible with your setup?
Also, did you have to do some serious pounding in the fender well or just light stuff??

As far as I gathered so far you're running 305/35/18 on 11" wheel w/ 38 offset
from what I gathered too, Jesse's running 305/35/18 on 10" wheel w/ 33 offset
so I guess the main reason for pounding the fender well in your case was the 11" wheels.

Due to my recent disappointment with local availability of tires I think I'll go a tested route and get 11" rims with the 305/35/18 555R's as in your setup. That will increase both my contact patch as well as the side wall height so my current 3rd gear traction problems on R888 295/30/19 will most probably be sorted.

I am running ~1.5 rear camber. We pounded the back/innner side of the well in a few spots. Nothing major, maybe 15 mins per side. Was not a big deal at all. I will send some photos over the weekend per your request. Also, referencing my prior post, I did measure to see whether the 315 40 would fit, in my seemingly neverending quest for 2nd gear traction. It was dark when I did measurement and I did not remove the wheel, but looks like it would easily clear in the rear/bumper area, but would just barely contact at the front near the skirt and just above on fender in a few spots. I'm sure I'm nuts but I'm wondering if there is a way that the fender could be radiused a bit to shave 1/8 inch or so and repaint to obtain clearance. Anyone done this or have thoughts??

With a 33 offset you can run an 11 inch rim also. This is at -.5 inch factory ride height.

Jake your camber is prolly the reason for bad traction, or atleast not as good as you can be with your tire. Go zero on camber and itll increase traction and extend tire life.

Thanks. I'd like to get some other views on that. The guy who set the car -drove professionally for 20+ yrs - indicated that this was better, b/c under load, a static zero setting actually becomes positive and reduces traction. I have no idea who is correct but would like to hear from others. Again, I have full traction in third. And when I spin in second, above about 1/2 throttle, it always tracks completely straight. I know of no one who has even close to full traction in second with the 6766. But I'm all hears.....

I meant traction. My phone changed it both times. Under load car squats causing more neg camber......neg camber is for corning. So on a real track or auto x you want neg camber. Straight line you want zero. Or even a tad positive.

Thanks, sounds like I need to have a conversation with my guy.... So you think this would make significant difference with same wheel/tire set up, particlarly in light of no one getting traction in 2nd with this turbo.

Jesse's right, but I think it's a bit more complicated than that and it has to do with both your camber plus ride height (which affects a few other suspension angles) when under load.
For more reading have a look here:

But DO talk to your guy and let us know as well as maybe he knows the E46 platform better ... who knows...

Hey Jake, I did a bit more research on this and apparently your guy is right.
Cars with McPherson struts (such as ours) increase their static camber under wheel load and apparently we lose about +/- 1 degree of neg. camber depending on the car's setup.

Here's where I got it from:

http://www.trackhq.com/forums/f295/s...704/#post74682

http://www.trackhq.com/forums/f295/s...704/#post74687

So I'm planning to change my 0 degrees static camber to -1 for my street settings and see how traction changes under full load in 3rd gear.


P.S: I also ordered a set of Hoosiers A6, in the same size 295/30/19 as my current R888 and I'm very curious how they perform given the same specs. I'm expecting the grip to improve to some degree due to the R888 being on the car for about a yr now but let's see. Will update.
