What is the lowest offset we can run? I want to run 18 x 7.5's with +35 offset....Someone help me out!

And how will the TPMS unit pick up the aftermarket TPMS's...?

Thanks in advance!

alot of hardcore suby owners will say in the 40s is better, but its really what u can fit under ur fender. i know alot of ppl are running low 30's and they look great, sit almost completely flush with the fender, u possibly may rub if lowered alot but i think it will be fine, make sure u post pics if u do cause i wanna do the same thing or just a 18x8.5 down the road

I have tried 18 x 8.5, there is rub. but on the 18 x 8, none. Rub usually occurs on the rear side. offset is at least 40.

So a 48mm offset will be fine? No damage to anything?

Yeah our oem wheels are +55, im looking at getting 235/40/18-8 with +45 off set, any one running similar or thoughts on fittment? I hadnt thought of the wheel bearings wear.

You'll be fine on a 18x8 with a +45 offset. For a 8" wide wheel the proper offset is within 43-47 IIRC. You should be fine.

I mean of course in regards to the wheel bearings. You shouldn't rub, assuming you're not drastically dropped. I can't be 100% certain though.

As for the wheel bearings though, yeah you should be fine for that offset :)

Well how about the rota g-forces in 18x8.5 +48 Running 235/40-18's? Oh, also I'm lowered on the spt springs
You SHOULD be ok. You might have to roll the fenders (maybe only in the rear).

A user on NASIOC "Nelly" has an 08 WRX and is running 235/40R18's on 18x8's, on Cobb springs. IIRC he said he had slight rubbing in the rear after he put the new wheels/tires on, but before the springs, only when the rear suspension was really loaded (people riding in the back/lots of cargo)

When he put the Cobbs on, he had to roll the rears. I think he got away with clearing the front fenders by adding negative camber.

Since your drop with the SPT springs is less than the Cobbs you might get away with a slight roll.

Shouldn't be too difficult ;)
