New Rota Fox 17 RSR rims are in

[911truther]

Now for the real dumb question with these 17 " rims on the 911 sc and with 225 45 and 255 40 tires the front offset is 35 and the rear 16 they said no spacers are needed is this in fact a true statement wheels are going to look nice I hope the spacers are not the next thing to order thanks

No spacers on the SC. Spacers on the flared bodies.

[Leebag]

I'll be interested with these wheels as well. Would like to see pictures in SC's.

I have used the Rota Fox wheels on my '87 Carrera for about 5 years, road and track, and am very happy with the looks and performance. To fill out the wheel arches, I'm using 21mm spacers front and 25mm spacers rear, with rolled fenders. I have Toyo R888 tires 225/50-17 and 255/40-17. No rubbing issues, but the clearance is tight.

[Mick_D]

Fly does your car have the widebody flares or just the standard body?

[lsf911]

Here is a picture of my SC with the RSR Rota Fox wheels, no spacers, 215s front and 255s rear. No fender rolling and no rubbing.

Mick_D, my car is a standard narrow body...

the fronts are 7.5"x17"ET35 w/21mm spacers, corresponding to ET24
rears are 9"x17"ET16 w/25mm spacers, corresponding to ET-9
tires are 225/50-17 and 255/40-17

Thanks FLy. I think I'm going to end up with those rims on my widebody with 30mm and 57mm spacers until I can afford $5500 for the really wide RSR rims I want and another $20K for the motor strong enough to push the wider rims. Could be a while

Wow - Fly, did you have to do anything else besides hammer that fender lip to fit the 17x9 -9???

I was under the impression that a 17x9 +15 is nearing the max us narrowbody SC/Carrera guys can go...

[Fly911]

I have only rolled the fenders, using a wooden base ball bat...
I also have a lot of negative camber, -3.5 degrees in the back, -2.6 degrees in the front. I would like to have -3.5 in the front also, but the camber plates are maxed out, so I will need longer control arms for that...
When I can afford it (...), I would like to have custom made (Braid) Fuchs replicas on 8"x17"ET 25 and 10"x17"ET-5, with no spacers, but the same tire dimensions, and also have 15mm longer control arms front. Having big spacers or big offset wheels in the front will increase the steering scrub radius, and give less accurate steering feel. By increasing the length of the control arms, and push the steering pivot point as far out as possible, I can get a wider track, more negative camber, and a MUCH better steering response.

Considering a 21mm spacer behind an ET35 wheel nets ET14, there is no way that spacer size is accurate for the front of a narrow body, regardless of camber--maybe with 912 hubs or something I suppose. And I'm also doubtful of the 17x9 ET-9 fitting, though with -3.5 camber that is doable. We are talking spacers on top of the stock Carrera hubs, stock flares?

these cats usually call total offset, so when he says 24mm it is 12mm on each side.

But still impossible on a narrow body, with those tires

[Fly911]

Hey guys, Bleedsblue and impactbumper! Do you think I'm lying? I know exactly what I have! The front spacers are 21mm on each side. The rear ones are 25mm on each side. the rims are standard Rota Fox. And the tires are R888 with those dimensions. And there are no rubbing issues! So it's fully possible!

I am not saying you are a liar, but sure calling you out on the fitment.

[Bleedsblue]

Neither am I--and I think the car looks spectacular with the fenders stuffed, Fly. You mentioned a net offset up front of ET24, which I'm guessing was a simple typo (should be ET14 no?) but I was wondering if you had a thinner spacer. Then, I made the mistake (my apologies) of thinking your front wheel was 8" wide; I'm personally rebuilding a set of wheels and will use a 7.5" ET17 up front (albeit with a 205), and I have -2ish camber, so your set-up makes more sense on second thought. I'm still surprised those 225s fit but more power to ya!

Cheers.

[Fly911]

Hey guys, just to clarify... I'm an avid DIY Porsche guy and I know what I have and I know what I'm doing. So the Rota Fox wheels do fit with the 21mm spacers front (that corresponds to ET14, that Bleedsblue rightly corrected me on...), and 25mm rear (corresponding to ET-9).
I have a 930 Turbo brake kit from VCI 930 Brake Upgrade 911 - Carrera - 914 - 914/6, but to my knowledge the hub offsets are identical to the original Carrera hubs.
The negative camber of 2.6 and 3.5 degrees f/r, makes a big difference on tire to fender clearance. I have also rolled the fenders using my wooden base ball bat, sticking it in between the wheel and the fender, and roll the car back and forth. It not only rolls the fender lips, but also pushes the fenders out. On my 996 I actually was able to increase the tire to fender clearance by 1" (25mm), but the 996 has thinner steel gauge than the 911. The 996 had 10"x18"ET65 as standard, I was using 10"x18"ET40 with no rubbing issues.
I'm not a fan of spacers, and particularly not big spacers. At some point I will have two sets of wheels (15" for the track and 17" for the street) with offsets that don't require spacers. But for now I'm happy with my set up...
So when my economy recovers after my $60k engine and gear box rebuild, I will buy new wheels!

I run 17x9 ET 33.5 (ish) up front on my narrow body.

If my math is right (questionable):

(38.1mm wider wheel / 2 = 19mm outboard of centerline)
That puts my outer lip at an equivalent 33.5-19 = 17x7.5 ET 14.5

Camber, rolled lips. So Fly 911s setup is completely possible. Just need the supporting mods (camber) to make it work.

[Bleedsblue]

^Yep, totally agreed, and in fact I will be using similar front fitment with my RS rebuild (albeit more narrow tires). Both of y'all are pushing the limits of fitment, good work!

[Driven97]

FWIW, I hit the wheel wells at full lock, so I'm slightly more than pushing the limits.

[Bleedsblue]

More like rubbing the limits

To be fair/for the purposes of the OP: as Fly notes, he is only able to fit such spacers under the Rotas with a combination of serious camber and rolled (slightly pulled) fenders. I think for a low SC/Carrera with stock-ish camber and fender lips, the Rotas will not need spacers of any sort. Agreed?

Side note: it kills me neither Rota or Euromeister make an 8" wide front fitment wheel for a narrow body.
