Pics after my 4.5 lug conversion

[M3 Ryan]

my work has 2 RZ's in new condition in their wheel inventory, and I highly doubt anyone will ever buy them, do you need another 2? they are all silver, 16" 5x120 not sure on the width or offset though...

I had multiple on-ramp unintentional drifts. I would be literally steady state at the edge of adhesion, then, with no throttle or steering change, the back end would come right out as if I just lifted. Honestly, quite dangerous; the first time scared the living shit outta me.

I now have 300/440, really thinking of putting at least 375 up front. Or maybe just staggering the tires on the new 17's. I'd probably get flamed for that one. ;)

Jay, I had similar experiences, mostly when the suspension was all or most of the way down (GC's). Do you think it can be attributed to the excessive rear toe? Or did you also notice it when the suspension is high (not slammed)

Well, I've never really had the rear that low. Here's where it was all summer, and when I had the scary snap oversteer:



5.5" rear springs, all the way up (2.5" perch). I would love to make a comparison now with the car high, but it's too cold for tires to provide the same lateral grip as the summer, I don't think I'd have a valid comparison. I think you're on the right track, in addition to the traits the trailing arm comes with.

Thanks guys.

Yeah, I have 2 more gold RZs to match the back two. I just need the extra lug holes to mount them ;)

I could take some more pics of the mounting plates of the bar, but the bottom plates are kinda messy since I sprayed them with undercoating.

As for the stability, driving with 475 springs in the rear has been fine w/ stock ones up front. The car is pretty stable. I think part of the reason why it's fairly stable is because the 205s I'm running on the 16s are slightly wider and stickier than the 205s on the 14s. I also put in solid poly mounts in the rear subframe and adjustable bushings in the trailing arms, with maximum toe out, minimum negative camber settings.

Jay: It sounds like your rear toe settings are off, or you have some rear suspension slop which is messing up your alignment in corner.
