Default s14 wheel/ tire fitment help

hey guys

I have been looking around the site and a few others but i'm not finding the answer i need . i'm really wanting to run a 17x9.5 18 wheel setup on my s14 with 255/40/17 at all corners . my problem is all the cars i find with this setup seem to have a koni shock setup or they are the drift guys with a smaller tire . does anyone have pictures of a s14 on coilovers and whats the inner wheel/tire clearance is like ? I do not want a crazy roll/pull on the front and rear fenders to the point it destroys the sheet metal .


car will be street driven to and from autocross / road course events .

front suspension / brake setup

stance coils
spl tension rods
spl outer/inner tie rods with bump steer correction
stock lower control arms with bracing and poly bushings

300zx 30mm calipers with 350z track rotors


rear

spl ruca
spl traction rods
spl rear toe rods
solid alum bushings in sub frame
stance coils

300z caliper /rotor

right now i have 17x8 +30 cobra r wheels with 235/45/17 tires

I don't have a picture of it the clearance with a tire on, but you get the idea of what you'll be working with. This is with MCS coilover strut body, which has standard length strut mounting tabs. Front is tight, rear has gobs of room on the inside to get away with a much higher offset.

17x10 +18 with 12mm spacer on front, 2.5" ID springs. I moved to 2.25" ID springs for more clearance. I'd say there's about 4-6mm of clearance now with tire (255/40 RT615k) and aligned how I want it:


Sitting (sorry for the black and white effect):




With that said, you'll be able to get away with no pull in rear with higher offset wheel. But, then you'll need to run different offset wheels front to rear and that's a no go for me. I need to be able to rotate all 4 corners.

With +18 in back, you'll absolutely need to roll and pull as you can see. Same goes for the front. Car is running -4* front camber and -1.7* in rear in those pictures.

I prefer to run the higher offset RPF1s (+38) and a spacer in front.

But I'm also just enough of a purist that pulling s-chassis fenders makes me sad as its irreversible lol.

My car is far from pure lol. What size spacer in the front do you run? But, you also have "Richards Housings" style Koni setup with the extended strut mount tabs? For me to run a +38 would take a ridiculous spacer in front.

I run a 15mm or 20mm spacer with 9.5 +38.

The ARP studs have plenty of length to use that sort of spacer.

You have extended strut mounts relative to OE?

Even with a 20mm spacer on +38 it still wouldn't clear the coilover with the strut mount length the MCS's have on mine.

Nope, just the normal koni housings, no extra modification.

With 15mm spacer it's *very* close. Needs like 16-17mm.

And this is a 9.5 +38, not a full 10.

My 'street' rpf1s are 9+22 in front with a 255 because it fits better. But this is also s13.

Hope this helps. 17X10+20 with 275 tire. I don't have pics but I did roll and slight pull on the fenders to stop it from rubbing later. Raised it up because of the tire rub. Rear is SPL stuff

Right, so a 10" would require another 6mm of spacer. That's a thick one! (TWSS)....

maybe i should just go 17x9+22 with a 255/40/17 wheel setup .
or do a 17x9+22 245/40/17 front and a 17x10+18 275/40/17 rear

i really hate to make the wrong decision and end up hating my wheel setup .
i also have arp extended wheel studs front and rear .
my alignment setup is this

FL FR
camber -3.1 3.1
caster 7.1 7.1
toe 0.12 0.12



RL RR

camber -2.5 -2.5
toe 0.02 0.00
