For those running a square setup, how do you like it?
#16
Imho the 50/50 weight distribution really lends itself to a square tyre setup. If you are building a high power car then get yourself at least 9" wide wheels all round. Personally I run 265/35r18 semi slicks all round and really like it.... enough rear grip for putting the power down out of corners, and enough front grip to put the big reds to good use while braking. Thinking of moving to some 17 inch slicks for track work this year though.

Is this for the track or the street? Do you have a turbo or NA? For an NA at the track, you want the lightest wheel possible. I ran 7x15 cookie cutters all around on my NA. A stock 944 understeers and rolls pretty badly. I corrected this with springs, torsion bars, and sway bars. It was then possible to dial in a very nice balance and fun car. It was not necessary to run a staggered setup. This is not desirable at the track because you want to be able to move tires around to maximize the life of the tires due to uneven wear.

Note that the widowmaker lawsuits were in full swing at this time. What was the HP of the first 930? What's the HP of the 951? The company as a car maker was on the brink of insolvency every day with those lawsuits hanging over their head.

Everything I read over the last 20 years, some articles contemporaneous with the release of the car (S2 89) said they are staggered in the US because US drivers suck. We cant control the car, so they killed the perfectly neutral handling and staggered the wheels so we get understeer. If we didn't have understeer we would break the law of physics.

And if lawyers have anything to do with performance limits on expensive sports cars, that would be quite ironic as I'm sure many of them go to court to make the money to buy those very cars....

Dont know. Pretty sure the Road & Track article from 88 for the 89 S2 discussed the staggered setup. May have been a different magazine that made the comment about understeer being made standard on US cars. .
The company survived because it did R&D for other manufacturers. The 80s and 90s were terrible for them. The steel strike when the Carrera came out hurt the ability to get aluminum for the wheels, the drop in value of the dollar raised the price of the cars and nobody wanted them, and the list goes on. The widowmakers ere the icing on the cake.

raising this thread back up.
I'm not looking for a square setup, but rather 8" wheels up front on early offset 951 struts.
I assume an 8x16 Fuchs wheel with 23mm will fit. Can anyone confirm?
along those lines, how about a 9" rear wheel with 23mm offset?

You should get 1986 944 Turbo Cup 8" Fuchs for the front and 9" 930 Fuchs for the rear. Very Nice look, superlight and the ET you want. Very hard to find but they come out every now and then.

I have been running square 15" phone dials with 225/45s for autocross and my car (late offset) is neutral with a tiny bit of oversteer, but I've updated most of the suspension based on recommendations I found on Clark's Garage. I recently purchased 16" narrow spokes (7" front, 8" rear) which I intend to try out this year (COVID permitting). Based on the results I may try to find another set and run square 8" all around with 245/45-16s.
There's a good source here for Porsche wheels weights that includes rim diameter and width, part number, and offset. Note the big difference in weight for some of these wheels. Wheel weight should be a major consideration for a track wheel. Many of the wheels on this list are very hard to find or very expensive or both.

I'm building a 924 Carrera GT replica using an 87 924S and early offset turbo struts/brakes, so I want the correct appearance with Fuchs but I want 8/9s instead of 7/8s for track use.
I've got my eye on some 8x16 Fuchs with 23mm offset and I'm pretty sure they will fit up front, just wanted to verify.
what's the offset on those turbo Cup Fuchs? I wasn't aware of those - only know about the 8/9 late offset magnesium wheels. for Fuchs, the offsets I've seen for 8x16 are either +10 or +23.

Yes, the 8" et23 Fuchs [951 p/n] will fit on the front of your 924 CGT. Those at the front, paired with 9" et15 Fuchs [911 p/n] at the rear, are what the Escort Cups ran in '85/'86. Note: 8" et11 Fuchs [911 p/n] will not clear 951 baby black Brembos.

Yes I got the 8x16 I was referring to. The project has been on hold a few months but will resume soon
