Default I'm new here.

I have 1993 SC300. She's slammed to the ground, and looking for advice on wheel fitment. Would 18" 9.5's fit in the front? Offset +25. Fenders already rolled.

You bought the wrong offsets for someone that doesn't want to stretch. You're probably looking at a 235/40/18 or 225/40/18 given the low offset.

I currently have a 20x10.5 square setup +31 front/+22 rear with 255/30/20's. Baby stretch imo.

Looking at a 20x10.5 +38 and 20x11.5 +30 setup. The fronts will be retracted by 7mm and the rears will poke 5mm more. I'm ok with that because the fronts are more aggressive looking at the moment. What tire sizes would you recommend with the new setup? Was thinking I would either keep the same 255/30/20 for the fronts but maybe downsize to 245/30/20. For the rears I was thinking either 265/30/20 or 275/30/30.

I just want to make sure the stretch is the same as I want it to look all around aesthetically pleasing. Don't want too much of a stretch up front and a beefier rear setup. I'm on coilovers and have aftermarket adjustability front and rear. Camber is currently at 0 front and between -1 and -1.5 rear with no wheel gap in the front and a slight gap in the rear for the raked look.

Any tire size help would be greatly appreciated. Thanks!

If I understand what you're asking for, you want the stretches to match front and rear?

Based on the sizes you were thinking of, I would do the 255/30/20 and 275/30/20.

Fronts: 10.5" = 266.7mm, so 255/266.7 = 95.613%
Rears: 11.5" = 292.1mm, so 275/292.1 = 94.14%

Those 2 sizes are the closest to matching in terms of stretching percentages.

Yes that's what I was asking, thank you.

No spacers needed, those are an aggressive fit. The fronts will poke a lot more than the rears, but those tires sizes should be fine depending on your ride height.

Didn't want to make a thread for this but can anyone tell me:

How wide of a spacer is required (a hubcentric with independent studs specifically) to be able to keep my stock studs as is?? is it as simple as measuring the length of the studs with wheels off or is there something else I'm missing?

I really do NOT want to have to chop them down to make this work.

A 25mm will clear the studs completely and make it like they aren't there.

For any size smaller than that it depends on your wheels. If the wheel is a dual lug pattern or back of the hub is solid and looks like this:


Then, the only bolt on spacer that will work is 25mm.

For 20-15mm bolt on spacers, then it depends on the depth of the pockets like in this photo:


The factory studs will fall into the pockets in between the lug holes.

You're the man! thanks. my wheels are pathetic so I'm probably looking at 25mm regardless.

yup. The depth of that window on the wheels is very important if using a bolt on spacer at 15-20mm.

On a side note blkexcoupe, I picked a set of ARP studs and will be going with your suggestion with pressing out the studs off my old spacer to convert it to a slip-on style.

Default This is how my setup is going so far.

215/35 18x9.5 +22

215/35 18x9.5 +30 all around. 1 inch spacers on the rear and half inch in front.
Probably should've put 40's or 45's in the back but it's all part of the learning process👌
