Will either/both these fit a 1990 944 S2?

Set of four Boxster S (986) "twists", 17in genuine Porsche wheels.

Front : 7in offset 55mm
Rear : 8.5in offset 50mm

or how about these:

Genuine factory Porsche Boxster alloy wheels and tyres, 17 x 9.5 (2), 17 x 8 (2), with centres, suit all 993 and 996 models, [...]

Both descriptions would fit.

some of the later boxter wheels will require a 7mm spacer up front to clear the hub.

Mark,

I have Boxster twists on my S2 - 7 x 17 et 55 on the front and 9 x 17 et 52 which fit well. The 7s are a bit narrow for the 225/45 fronts - I would prefer 8 inch fronts. For the rear the 9s are perfect for 255/40 tyres, although I think 8.5 would probably be OK (8.5 inch is the min width for a 255 tyre). The 7's fit under the guard with plenty of room, but the 9s are pretty tight. You will need to watch the offset for a 9.5 inch wheel - although if the offset is correct I know these will fit.

even if the wheels fit, you may not be happy with the tire choices.

if you stuff a 225 on the 7s, you will want to go thinner on the rears with a 245. if you put the better looking 255s on the rear you will have more understeer. i played with a few sets of boxster rims and ended up going back to the stock 16s. the car just drives better with four tires the same size. my 951S has the 7/9 setup and i dont like it.

Interesting. I'm running 225/45/17 and 255/40/17 on the S2 at the moment... I quite like the handling, but I've not compared to the stock set-up.

BTW, stock (on my S2, at least) was 205/55/16 and 225/50/16, on 7" and 8" rims.

I was toying with the idea of getting a second set of wheels for track. The two sets of Boxster wheels are available for sale at the local club.

Will Boxster S (986) "twists", 17in genuine Porsche wheels fit on an '87 951. They should since the suspension and brakes on an s2 are the same as a Turbo.

Is this correct thinking?

The 968CS came standard with 225/45 and 255/40 17's and I don't recall anyone saying that these have any significant understeer. I guess it really depends on the suspension setup. I have adjustable rear sways and can get the handling fairly neutral - however the 225s do move a bit more than I'd like on the 7's hence my thoughts that 8's (which I think the 968CS had) would be better.

i found that any more than 22cm of difference between front and back and you feel the understeer more. on the street i had 225s all around on my last S2 and it was great. I had 225/245 on the track tires and it had a little more understeer.

my 951S has staggered and i dont like it as much as four of the same. significant? that's been debated to death here. my post was just an FYI because in retrospect, i was not fond of the boxster setup i had on two of my 944s, and prefer the same size all around. YMMV.

Yeah... the front wheels will bolt on, but the center caps will not fit unless you have the spacer. At least this is the case with my 968 and 2001 boxster wheels.

Which boxster wheels came with 9.5" and 8" sizes? I want those!
