2" wider front fenders with stock rear

[PDX-944]

Im trying to envision what it would look like. I don't know if the rears are wider than the front, I assume so.
so would the 2 inch wider fronts look weird with the stock rears, or would it square things up some?

The point is, for my 951 I can fit 295 in the rear no problem, but I cant fit that much in the front.
Inherently the 944 needs a pretty square setup. if I get camber plates and adjust it just right and throw hard suspension on there it might work with 285, but id rather not go any stiffer than I have. if I had a little more room in the front it would be a lot more flexible. ill be running 10" MY02s all the way around. they fit with 225s, but that's not near enough rubber. I have 4 sets already of 315s, 295s, 245s, 235s. 315 and 295 would be more like what I want. 235 isn't enough, 245 is pushing it.

Hmm these specs for theTurbo S seem to indicate that the rear is in fact narrower than the front
Wheel track, front: 57.40 in. / 1457 mm
Wheel track, rear: 56.50 in. / 1436 mm

You can fit 295mm up front with 2.5" coilovers. I used 17x11.5" up front with 275/40-17. The taller tyre would rub the fenders if I had the steering turned more than 90-degrees when hitting bumps. Also rubbed the brake-line at full steering lock. A stock diameter tyre wouldn't have these issues.

I fit 285 on, tested without driving. It was close though.
I guess we'll see!
Now, to fit 315s in back. ..

[PDX-944]

So I (double) confirmed that at least 295 will fit in the front under stock fenders. That's good enough for me!
That's a big leap from 225

Yeah! Really helps cornering with fatter tyres in front. The best 16" set-up I had was with 16x10" all around with 245/45-16 tyres. Then I tried 17", but couldn't get wide tyres in stock diameter. Looking at 18x11/12" next.

Paul Bloomberg had 335mm tyres in back on 18x13" wheels.

Im pretty close to max on stock fenders haha
I have some my02's that I can have made into 11 12 13 whatever size. Id probably have them made and sell them to 996 guys though. No need for that really lol

It will depend on the camber, spring size, wheel offset and the idiosyncrasies with each car and their front fenders. (I've found that many cars seem to have different clearances) In my opinion, 295's will be really tight under stock guards. You will definitely have to roll the inner guards too. By fitting 295s on 10"s you will bag out the sidewalls. I ran 275s Nittos all round on 10"s and had good results with them. I did try 285 Hoosiers and they did work but that's as wide as I'd say are suitable for a 10" rim.

We run 295s all round on our car now but that's on 11.5" wheels. They are neither bagged or that stupid stretched look. On a 10" wheel I would say you will get overheating and premature wear as they roll around across the rim laterally. I say you would get better grip with smaller than 295s up front on 10's. Tyre choice is more important than just fitting the widest rubber possible for the sake of it. I do agree with running a square setup though.

i have the Turbo S, so no fender rolling is needed, theyre already rolled. 285 had plenty of room. I currently already have 295 and 315 tires, not mounted. the 285s are actually slightly stretched to fit; 295 should be pretty square on the rim. the 315 will be a bit of a stretch (opposite pun noted), I might send my extra wheels out and having a set of 10.5 or 11s made. I could even make 2 sets of those...

until I stiffen the rear to match the front better, the extra roll may actually balance things out for me. currently I have 400lb in the front and stock turbo S in the rear. not my doing, and not a great choice.. im slowly making this thing right in the head, and hips. doing some motor work this winter (downgrading turbo size, etc). next will be suspension. ill keep an eye out for better size tires, but I couldn't pass up the deal I got on these

When I had 275s in front, they rubbed on the brake-line bracket on the inside at full steering-lock. I just chopped it off and welded it back on about 2" further forward. This was more of a problem with taller-than-stock diameter than width though.

Having wide tyres squeezed onto narrow rims makes the car's turn-in response nervous and heavy at the same time. Kinda like wrestling a greased pig and trying to make it stand up and dance!

A square set-up of 295s on 18x11.5" sounds perfect. I'm going to have to get a set for myself.

I had what you guys call a Turbo S (only released in the USA. Everywhere else it was just an '89-'90 turbo) and while the guards are pre rolled, I still needed a guy to come in and 'massage' them to fit anything wider than 275s. However, as I mentioned, it comes down to the whole package. The wheel offset being crucial in all this.

If you don't have a massive budget I would work on getting the suspension sorted before putting extra wide fenders, wheels, tyres on there. The suspension will improve the car more than those other things at this point. If you can afford to buy a complete system like the KW V3's or better you will be way out in front.

315's on these cars is a waste of rubber in my opinion. Too much rubber can actually be counterproductive. You won't get these hot enough to make use of that rubber. If you have less than 400bhp you can easily get great results with 4 x 10" x 18" and 275 Nitto NT01s all round. I had great success with this setup back when my car was a lot less modified than it is today but still more modded than yours sounds to be currently.

You can see that the 295's on 11.5" wheels sit nicely. Not bagged or stretched.
