ok i just bought a set of Saleen Wheels here are the size and the offset.


SIZE AND SPECIFICATIONS: The front wheels are 18x9 with a 24mm offset and the rear are 18x10 with a +22mm offset. The lug pattern is 5x4.5 (114.3mm).


i know i have to do a 5 lug swap on my fox, but can i run a 10in wide rear rim with out any problems/? or should i call and change to 9in wide all around? i need help soon before they ship them any input will be much appreciated. thanks

 

10 inch will fit but it must have a 6.5" BS when using the stock spring location or 6" BS and using a true 10" wheel,.. not a 10.5" wheel when using coil overs. Not sure how that equates to mm in offset. You will need to remove the quads to run anything wider than a 275 tire back there also. I've seen 315's fit but not on all wheels. Some will rub the fender and on 87 - 93 GT's the ground effects like to rub on large wheel and tires also.

Also,.. not sure how your rear suspension is set up. But if you run coil overs in the rear in the stock shock location,.. 10.5 inch wheels wont work. 9.5" - 10" with a 9.72 - 6" offset and no more than a 285 tire or else they rub the springs on the coil overs in the rear. You can run 9" wide wheels with 245 or up to 275 wide tires up front with the stock suspension. But if you go with coil overs up front,.. no more than 8.5" wheel and a no more than a 245 tire or they will rub on the coil over springs. A 1/2 inch spacer works up front with 9" wheels and 245-275 tires,.. but not in the rear. A spacer will put the wheel and tire into the fender with a 10" or larger wheel.

Also when doing the 5 lug swap in the rear. Just do the axles and use 'FOX' length axles. Do not swap to an SN95 rear or use SN95 length axles. SN95 and Fox axles housings are the same width. How ever,.. SN95 axles are 1.35" wider on each side to have room for the ABS exciter ring. Fox length axles in an SN95 housing wont line up with the Disc brake caliper brackets. Will put the rotors inside of where the calipers are. Taking SN95 disc brake brackets and flipping them for use on Fox axles works. Else just use the drum brakes. Unless you are road racing you will not notice any better stopping with discs on the back vs drums. The front brakes do 90% of the stopping. Swapping to 13" SN95 Cobra spindles and brakes is a simple bolt on. Just make sure you use the Sn95 lower ball joint or you will need washers to shim up the stock ball joint for the nut to secure it.

I recently converted my 93 from 4 lug back to 5 lug again. But this time the car has fox length axles using drum brakes.

This was my car with 5 lug and Cobra IRS on the rear. 17x9 wheels and the rear rubbed like a SOB. Just too wide with out modifying the fenders.




.

The car was converted back to 4 lug and is now 5 lug again,. but now the using the proper width.
Using American Alloy Fox width axles on the rear and Ranger drums,.. it was a simple bolt in procedure.

Back to 4 lug.


.

And now back to 5 lug again. It was as simple as swapping the drums and axles. Thats it.






.

Doing the front was just as easy.
Removed the tie rod end and lower ball joint. Removed the 2 nuts and bolts holding the strut to the spindle. Swapped the fox spindle to SN95 Cobra spindle.







These pics were just a trial fit for the front. They have since been cleaned up. New Cobra PBR calipers and 13" drilled and slotted rotors have been purchased.


.

The spindles have been cleaned up.




.

These are the new rotors that will be used.


.


This is the stock Fox ball joint when used with the SN95 Spindle. The spindle sites too low on the bll joint for the nut to lock down on it. The top of the ball joint 'almost' hits the bottom of the strut. The cure is to use washers to shim the spindle up,.. or to do it right just buy the Cobra ball joints.


.

Also,.. this is the rear. The wheels are 4 lug 17x9 Cobra-R replicas with 5.76" BS. The tires are 275/40's and as you can see,.. there is no way a 10"+ wheel or 315 tire will work back here with coil overs in place.




In order for me to use a 10" wheel and wider tire back here I would need to remove the coil overs and put springs back in the OEM location over the rear lower arms.
My plans are to go with a 18x10 wheel with a 6" BS and 285/35 tire. To prevent fender contact the fender lips need to be rolled as the clearance will be tight. A 6.5" BS would put the tire on the springs with a 10" wheel. With no more than a 6" BS it gives enough room to clear the coil overs yet still snug inside the fender. Thats as wide as you can go with this type of set up and not flaring the fenders.

Edited and corrected.

Great write up, Jim ... again.

 

Hey Greg. Thought about calling you a couple times but couldnt think of anything to say. If you need anything give me a call. I'm not much for words of wisdom when it comes to emotional issues. But you have been in my thoughts and prayers and I'm a good listener.

Correction- 6.5" BS on a 10" wheel with 275's and stock springs work like a charm

 

Is that BS you typed correct?

 

Doh,.. I posted that at something like 2am. Couldnt sleep. I corrected the post.
9.76 BS would put the inner wheel lip to the other side of the shocks,.. LOL.

90% sure it was 5.76 BS,.. Might be 5.72. I know its 5.7x. I would have to look on OE wheels site and look it up again to give you the 'exact' number.

Um,.. isnt that what I basically said in my first sentence?
Get some sleep Thomas,.. your comprehension skills need to catch up with what your eyes are reading.

17x10.5 with a 315 tire will work on stock suspension with the quads removed and the fender rolled.

Unfortunately I dont know of any 4 lug wheels in that configuration. Only 5 lug,.. and as a result you will mainly find wheels with either the S197 or SN95 offsets.
Need to be careful when buying wheels because many styles come in both offsets.

This was my son's car as we sold it.
Bone stock rear, quads still on board.

275/40 17x9 wheels with 5.79" BS on the rear.
Fronts were 245/45 17x8 wheels with 5.5" BS.

 

I highlighted the areas that I was refering to. Uless I reading it wrong, some areas area contradictory. Not picking Jimbo, just clarification. The first sentence does say 6.5/10 the you say 6/10, then the last highlighted is real confusing....9.72-6" offset?
I have true 10" wheels with 6.5 b.s. with no issues and stock spring location

 

Re-read it again Thomas,.. here perhaps this will help. I highlighted what I am trying to emphasize. Maybe you can understand a little better.

10 inch will fit but it must have a 6.5" BS when using the stock spring location
or 6" BS and using a true 10" wheel,.. not a 10.5"wheel when using coil overs.

.

But if you run coil overs in the rear in the stock shock location,.. 10.5 inch wheels wont work. 9.5" - 10" with a 9.72 - 6" offset and no more than a 285 tire or else they rub the springs .
