Ordered 255/35 and 275/35 hankook.
Falken has 285^30 avaiable and i believe federal as well. I think i might need a 5mm spacer for the front. What u think?

getting ready to make a a purchase wanted to talk to some knowledgable about the s14 chassis, Rims in mind XXR 526 18x10.5 +20 on the rears, im trying to run at least a 265 or 275 tire with hopes of fitting a 305 . I used the wheel calculator and according to this it states inner clearance 1 MM more, im assuming that means I need one mm more as in a spacer?? and for the outer extend an extra 39mm. Im a little lost. Can someone shed some light on my situation. I wanna run some wicked wide tires but not hella flush bullshit or tires sticking out of my vehicle by 2 feet either. If fenders need to be rolled sweet otherwise what do I do.....besides choose different wheels!!

My question is, how far can rear overs be "bowed" out? I have seen many different setups run with the overs, and all I'm really going by right now is pictures which is not the best thing to do.

I figure if I go aggressive I might as well get a setup that I will bow the fenders to make fit instead on getting a less aggressive wheel and messing around with spacers and whatnot. I'm also not looking to run a crazy amount of camber either.

I was thinking about picking up some Equips but the rear sizing is 18x13 -18 I believe. Now, I have seen another s14 with the Chargespeeds running an 18x13 -10 Wed wheel. Doesn't look like too much camber, but the car is also way lower than I am. I tried contacting the owner about alignment specs but have gotten no answer. So any help from the overfender experts would be appreciated. Thanks.

Personally, I would have looked for 70mm in the rear just to be safe. You can't really just throw a random number out there and say well they should bow out 50mm more. All depends on how thick the fiberglass is and what the actual measurements of the fender really are. Just cuz they said 50mm, doesnt mean its exactly 50mm.

Also, which Chargespeed fenders?

And I want to run the minimum amount of -camber possible. I know that a roll/pull will probably be needed but nothing to drastic. Any advice would be appreciated.

Should clear no problem...

Wont really know till you put it on. If you dont want to run spacers, you can always slot the strut/knuckle mount out so you can pull the knuckles away from the strut.

Rears are 18x10.5 +22

Fronts are 18X9.5 +12

I'm on Stance GR+

Ideally I would want to run a 225/40 up front and a 265/35 in the rear. (Achilles ATR Sport)

My overall goal is to run minimum camber in the rear. I don't mind running lots of camber in the front. I would also like to keep my metal virgin. I don't mind rolling the lip in but I would like to avoid a pull. I know I won't have issues in the front. But the rear does concern me. What do you fellas think?

Considering how wide of a tires you want, you'd need to pull the rears if you dont want to run alot of camber.

fit on stock metal with just a good roll possibly slight pull or raise the car some?
I have stance gr + pro coils spl rucas
also what ideal tire size on this? I don't want a stretch i want as much tire as i can fit while not throwing the speedo off much if any.

Well, you need to make up your mind. Are you gonna lower the car and have tires within 1" of the fenders? If YES, then you'd need to stretch som tires. 225/45-17s all around. If you also want to run wider tires than that, you'd need to pull the fenders or run camber. I'd go with something like 235/40-17 up front and 245/40-17 in the rear.

No, the calculator is using whatever wheel specs you put in originally and calculating how the new wheels will fit in reference to that. So with the calculator saying that you will get 1mm more clearance inside, its saying the wheel lip inside of the new rim will be 1mm more AWAY from the suspension. So you actually gain more space inside. The outer extending an extra 39mm means thats how much further the new wheels will stick further out, in reference to the original wheels.

Picked up the s14 chargespeeds from Ray (frizzle). And I see what your saying. FG is FG and no one mold is going to be 100% identical. I won't be heart broken if the wheels don't fit. I'm really just looking for a lip which could also be achieved with a negative offset 11 or 12 as well.

Well, if its chargespeed, then you might be able to flex them more than a US copied fender. JDM kit companies usually lay their fiberglass thin and more flexible than the US ones.

I say, get the wheels you want on, cut the stock fenders, get them seam welded, test fit the fenders with the wheels on so you can see if you'd have to run some camber. Depending on how far out the tires stick will be dependent on how much camber you'd need and how much you'd have to bow out the fenders. Finding that happy medium between bowing the fender and getting your alignment dialed in is where it gets tricky. In an ideal world, you get your alignment done and then get your fenders to fit your setup (wheels/camber).

Yes, it is going to be tricky. I'm only at -2 camber out back right now, and I know I'll definitely need more than that. But I don't really want to run a crazy amount like -5 or more it just doesn't look right to me. And if I get them and don't like how they fit it is going to be pretty hard to turn around and sell them.
Not many folks want to try and fit an 18x13 lol.

This is the car I was going off of.




He is running 18.13 -10 Weds. I tried contacting him twice, but received no answer. Now the equips are -18 but this gives a pretty good idea of what I'm trying to acheive and the camber out back doesn't look excessive at all.
