My point was the comment didn't seem relevant since spacers don't change the suspension geometry, if indeed the reference was to bump steer. In regards to bump (i.e. compression and rebound), although one could argue the increased width would act like a longer lever arm and affect interaction with the spring (rate), I suspect it would be nominal and somewhat independent from the action of the dampers. Still, calculations could be done to verify...

Not trying start anything - I'm just explaining myself since my sense of humor doesn't always come across as I intend it on the forum. ( I'm still not sure what you meant since you didn't explain how spacers and compression are an issue.)

I put the 18mm's on and I think they look fantastic.

FWIW If that's all you meant then just say so instead of alluding to some technical phenomenon ambiguously labeled "compression" or "bump".

Just say: "Be careful the spacers aren't so thick they push the tires out beyond the fender edge or it may cut the sidewall of your tire when the suspension compresses over a bump."

Clear, concise, helpful - even if it is somewhat obvious.

They are ET-47 7.5 in the front and ET-62 9's in the back - they look to have moved the wheels out about one inch both front and rear. Odd because the standard offset was ET 55 so the rears are adding 7 mm to the offset - but the front are just compensating for the extra half inch width. I added another 3mm spacer to the rear and that looks good but I would not go wider as my PSS9 suspension is set to GT3 ride height. So my guess is... front plus 5 mm and rear plus 10 mm is about right for me.
