No worries, I'm sure you will. My biggest problem has been the rubbing in the front. I can still make full-lock u-turns at good speed, but I rub the bumper tab like nobody's business on dips (18x9.5 +30 all around with 245/40/18 all around).

If I had to do it again, I'd get the bumper tab relocation done and extra metal directly in front of the wheel ground down before slapping the wheels on. I'd also get stiffer Swift spring rates (12k 10k currently) and Megan camber arms up front (SPC balljoints currently, barely any adjustability at this height).

bcr? swift springs? custom rates? ;D

9.5 +35 with 225/40 shouldn't have any rubbing until you get really low. You should be able to run zero to .5 degrees of negative camber without issue.

Sorry to bring this thread back up. But i recently dropped my is 250 awd. On bc coilovers. I dropped the car enough where there no longer is a wheel gap. But im having this wobble/shake/skippin coming from the back of the car when accelerating. I checked the car a bunch of times now but find nothing wrong. I read on forums that its a problem dropping this is250 i wish i would have done my research before doing this. Just wondering if anyone has experienced same and maybe found any solotions ?

Please and thank you

When I dropped my IS250 AWD about the same height, I got a minor vibration, but it was only when I was sitting at a stop light, which is the common issue most people reported (from what I remember at the time). I don't think this is related to that.

Have you gotten an alignment to make sure toe and caster is within spec?

The lowering might be an issue if you have an AWD model; something about the half shafts and the angle they do not like when being lowered. But yes, an alignment is HIGHLY recommended after the installation.

I have not gotten an alignment yet. But i plan to do that by this weekend to see if that helps at all. I do get a small vibration when standing still in gear but nothin really concerning. I spoke to someone over in bc racing and they said it might be the rear axels are bent more then a 45 degree angle and that might be my problem. I might just raise the back a inch more and see if this helps as well. I appreciate the help. Will keep posted

Saint360

Appreciate the help and reply. I will get an alignment soon. But im pretty sure its exactly what you explained. I plan to maybe raise the back an inch more hopefully this solves my problem a bit atleast

From what I read its about 26.00" from floor to fender. For the sweet spot. Probably will depends on the wheels you have too. I'd personally do about 27.00" all the way around as I'm getting old. I really don't care anymore about fender gap.
