thanks for the quick reply Josh!

 

sorry double post!!

 

18x9 18x10+13. I have been looking through and found a couple people who have managed to run these sizes (even lower offset in some cases) on stock fenders will a roll. I just need to know what is needed to make these fit. I'm rolling my fenders and wheels have 215's up front and 235's in the back. Im on coilovers currently. need help asap I wanna know for sure that i will be able to fit these before I buy them, or before someone else does. Thanks in advance!

 

Well, in that case, for the purposes of the Redline Time Attack Street Tire classes, what is the most you can stuff into the FC wheel wells at a decent camber angle (-3.0 front, -1.2 back) without having to go with overfenders?

 

255/40/17s in front and 275/40/17s in the rear can be done with the right wheels and offsets. You will need a fender roll front and rear.

I believe that the largest size Redline allows in street class for a RWD car is 285.

I run 17X9 +24 all around with 235/40/17. I run -2.8 camber up front and a fender roll. I have room for 255/40/17s up front.

 

What suspension are you running?

Would you mind sharing your wheel type, size and offset recommendations to make this fit?

 

I have BC coilovers. Wheels are '95 Mustang Cobra R 17X9 +24. If you can keep the offset near that, you *should* be able to get 255s to fit with little to no rubbing.

The critical strut to wheel/tire clearance is going to change a bit from coilover to coilover, even with the same wheel, so results can vary. I can take some pictures of my clearances later this morning for you.

 

Thanks.

I'm still searching for a coilover configuration from a reputable shock valver that has adjustable lower mount. I might even opt for a custom setup with 2.25" springs for even more clearance.

 

Mine have adjustable lower mounts.

Custom valved Konis and Bilsteins are the best, but I would say they are only 10-15% better than some of the coilover setups that cost 30%-50% less. And yes, I have run both. Obviously with those there are no adjustable lower mounts, you adjust height with preload, and spring length.


Going to 2.25 springs might be really tough. I dont know that many (if any) quality struts are small enough.

 

Here are the pictures. The closest point is the lower spring perch and the edge of the rim. They are 1/2 to 5/8 inch apart. 10 mm more of tire on the inboard side (a 255 would add 10mm per side) should not be a problem, as there is more clearance above the rim. Also there is room on the outside to go with a slightly deeper offset. Again, this is a 17X9 +24 wheel with a 235/40/17 NT05 tire.

An Enkei RPF1 in 17X9 +22 would be an ideal rim here.
Cheaper alternatives are MB Weapons and MB Competitions. Both are available in 17X9 +17. There are also +27 versions of these wheels that might work as well, but will slightly reduce strut clearance.

The problem is the front though, but having a smaller shaft in the rear won't harm things either.

How much more offset do you think you can use? 4mm? 8mm?

 

The rear is not critical. The tire will hit the rear suspension arm before it ever hits the spring. I was speaking about the front in particular.

I would say no more than a 17X9 +17 MM or so but that will depend on the tire size.

 

I just put 215/40/18's +35 up front and 255/35/18's +35 out back and had to do no clearancing whatsoever. i have about a milimeter between the tire and shock up front and i dont rub fenders anywhere. i'm only running coil springs right now so things may change in the future but these tires with these offsets worked perfectly for me... hope i helped

 

I've been thinking of getting a set of Mustang SC wheels, I really want to have 10x17 front and rear with 235/40-17 tires probably could stretch a 215/40-17 tire on the front ones.

What do you guys think of running either:

Package 1: 10x17 +20 235/40-17 F and R (Can i pull it of with a fender roll? A bit of crunching on the wheel comparison I need 6mm spacers up front to clear suspension. Don't think I can pull it of up front with 10" on stock fenders, if you have seen it done please point me in direction of a picture.)
or
Package 2: 9x17 +24 215/40-17 F and 10x17 235/40-17 R (Probably fit just fine? or a 5mm spacer in the front. Have seen 9x17 +0 with 215 on stock fenders.)

Here's what i've got.

17x9.5 +15 f/r

Fitting the rears isn't going to be a problem. I need a spacer anyway to match my pull i did for my previous wheels.



Anywho, my last set of fronts were 16x8 +0 with 205 55 tires. Tire sat tucked barely under front fenders pulled to the max and i cooked a bit of paint on full lock and had the raise the car up a few mm's. Rim was flush, edge of the tire was flush. I loved it. Excuse the ratty pulled off side moldings and mix matched pannels. She's a work in progress



I was wondering what tire size i'd have to run without spacers to get the same fitment. I want to run 40 series around a 215. What am i looking at? I'll probably test fit the wheels up tomorrow and see what kind of clearance i have with my camber plates maxed out.

Is my wheel going to hit my lower control arm? I have an angle kit as well. Not knuckles. Just extended tie rods. I didn't measure clearance with the 16x8's but i wasn't hitting the lca or coilover at all.

 

Is the image of 9,5x17? I will get a set of 9" for the front, I drive like a maniac so don't need no fender rubbing while drifting.

 

Hi all, Im a bit new here but have read the entire thread and just have a quick question. I just got a set of 99 GT mustang wheels for cheap. I think these are 17x8 with a +30 or 32 offset. My question is will a 235 40 tire fit on there?.. BTW im on stock struts with coil springs... Thanks in advance for helping out the newb!!

 

martis... in the front not sure, in the rear, no problem i'm running 275 nitto's on 8.5s out back on a 40 mm offset haha

 

Yea the front is what im worried about... tons of ppl run 225 45 so im thinking a 235 40 will work... at least I know the height is a bit shorter... idk about clearing the strut tho...

 

Yea those tires will fit. The wheels are 17X8 +30.

 

Ok, thanks LargeOrangeFont!!! Just wanted to make sure it would clear the strut... Do you think I will need to roll the front fenders to prevent rubbing... I am lowered on tein springs

 

No, that's a 16x8 0 offset.

I'm trying to get a 17x9.5 +15 to fit in it's place without running the inside rim lip into the lower control arm..... I think i might get a 10mil up front. I've seen people fit 17x9 0 offest but wasn't sure about the lca clearance with an angle kit.

 

Does anyone know about the above? BTW the rear tyres are 255/35 not 265/35 as originally thought.

 

Oh, so you're running a 9.5 up front and felt the need to look over my post. Thanks.

I'll fit my wheels on my own.......

Asking for help on this forum is like asking a 5 star hooker for a four hour freebie.

 

Buy a ******* calculator and learn to figure offsets on your own like most of us. Then you can go help out others that ask the same questions 178 pages over. FYI, 17 x 9 +22 with a 245 tire will clear the stock inner suspension.
