A 18x10.5 with a set of sticky tires helps a lot.
The 18" rim really helped me a lot. My IRS has only hopped twice since going with the 18" out back.
Solid bushings and a hard launch kit really help a lot to.
Don't go past a 295 tire! If you do, it's time for some spacers. If you don't drive the car much, I highly suggest the 18/295 BFG Drag Radial.
If you drive your Cobra a lot, I suggest a good 18/295/35 tire in the back and keep the 275 tires up front.
As you already know, none of this stuff is cheap. Income tax refund time is coming.. Go through the TireRack !

There's no easy answer to your question! First off, stickier tires will improve traction and CAN help reduce overall wheel hop, but there's no guarantee that will solve the problem completely. Polyurethane bushings, differential brace, and stiffer valved shocks all help to reduce the hop.MattM said:
You can safely fit a set of Nitto 315/35/17 DR's on your stock rims if you want to go that route. That would be an inexpensive way of determining if you want to go even farther with your quest to reduce wheel hop, because it sure as hell won't solve it by itself!
Do a search here in the Tech area for wheel and hop. There are a couple dozen posts referring to wheel hop and ways to combat it.

I agree..
To curb the wheel hop there are many things you can do. Larger tire diameter is just one that worked for me. The cure of the problem rested with my driving habits. I have not experienced wheel hop for more than a year now.
A few weeks ago, I purchased a solid rear end. Its going in next month.
if it's not your DD and you wanna keep the stock rims, I highly recommend the Mickey Thompson 275/40/17 drag radial, these are the best drag radials out there, except they dont offer them in 18's yet...If it is your DD, then i'd suggest some BFG KDW's, they're a little softer and will still hold up in the rain. I suggest to all of my customers going high in the HP range to have a second set of rims to put some drag radials on b/c it's hard to get 500hp to stick on the street 
i have heard of clearance problems with 315's on stock wheels. dont recall if they were nitto's or not, even 295's on 18s have hit before. each irs seems to be quite abit different. if your changing tires, just be prepared to grind the bolt head down from what ive seen.
of course this varies with tire brands as some are about an inch wider then others in the same size. im just hoping my 18" saleens with a 295 bfg clear without grinding the bolt head.

315/35-18's? That's a VERY unusual size.O.D. Showtime said:
A lowered car can cause rubbing on the fenderwell lip depending on the width of the tire you choose. You may need to have the fenderwell rolled.
An 18 inch rim clears the IRS better than a 17 inch rim. There are a lot fewer tire choices for 18 inch rims vs 17 inch rims.
Since all 315 tires ARE NOT the same width (it can vary as much as an inch!) you need to tell us what size rim and what size and what manufacturer tire you're trying to stuff in there.

a 295 fit nicely under my wheel wells, no rubbing unless you hit a hard bump with those H&R supersports
around town it rides alright.. coil overs in the rear would be best

18's
coil overs on the street ride nice
more choice on springs, they are easy to swap out, right height is easier to adjust and the adjustability of the strut is always there.

Based on research I've done, it doesn't appear as if a 315 tire is going to fit an SN95 mustang, assumming the car is lowered 1 1/2" or more. I suppose a 295 tire is my best bet. You guys with IRS can fit the 315's. I also need to take into consideration my bigger, aftermarket catback, which may supposively get in the way of a 315 tire. It's definitely possible to put a 315 on, but it will require me to flip or remove my quad shocks and put up with occasional rubbing under hard cornering. Figured I'd let anyone else interested know.
