Biggest fikse fm10 on carrera?

[ken_xman]

Whats the biggest 17"fikse I can fit on the 87 carrera?
Is it 8 & 9's with 1-1 1/2 neg camb, and rolled lips?

[Eric Coffey]

Probably 8's & 9.5's with custom offset/backspacing. You might be able to fit 10's in the rear, but you'll be rolling lips, moving oil lines, shaving spring plate bolts, etc.

8.5 Front, 10 Rear.

Well, there you have it. Randy would know!

Fikse's recommendations are 8 and 9's. Like everything else, some may be able to cram and extra 1/2 inch in some places. All I know is you can take 8's and 9's and bolt them on. I've done this to 2 Carrera's. I guess it depends if the possibility of extra headaches for 1/2 inch is worth it.

I would dearly love to know what o/s and what other mods were done and what trires are used to accomodate that fitment.

It's hard enough to get 8 & 9 to fit w/ the bigger tires.

I have 9s and 11s on mine... but then again... my fenders are a little bigger than a carrera's

[ken_xman]

I just ordered the FM-10's 17" 8 & 9 with speed silver finish
with Yoko AVS 100's 225/45 and 255/40
All from wheel enhancement. Dave was very professional and helpful. Highly recomended.
In 4 weeks I will post a pic.

Like Randy and bunch of others in the PNW, I have 8.5 and 10's on my Carrera. Fordahl Motorsports has the correct offsets. They are tight requiring rolling fender lips, removing dust covers from the front shocks, moving oil lines in the rear, etc, etc.

[Randy W]

Yup, what Doug said - this is max for:

Carrera bodywork or LWB narrow body with RS flares:

Front - 8.5x17 Fikse with 245/40-17 Hoosier: remove dust covers on sport shocks or use JRZ, 2.5 degrees neg camber, big torsion bar and sway bar, roll fender lip, shave front fender/S spoiler junction, use aftermarket fan behind RF Carrera fender cooler - still may have rubbing on inner fender lock to lock.

Rear - 10x17 Fikse with 275/40-17 Hoosier: move or re-route oil lines on RR, shave spring plate bolts, flatten '72 thermostat wire clasp and re-route wire, big torsion bar and sway bar, roll fender lips and tweak flare, 3 degrees negative camber - may still rub oil line a little and may burn paint.

There are similar cars that do not need all these mods done and can still fit this wheel/tire combo with no rubbing anywhere. This is what I did to get there, your results may vary.

[Bill Verburg]

Once again everyone is avoiding the issue, what o/s? Please?

I have 8 & 9.5 w/ 235/45 & 275/40 did all of the above and have the absolute min clearance on all sides of every tire

[Bill Verburg]

Here are some fitments where the #s have been provided by the folks that are using them, all additional donations of data gladly accepted

Bill:

When I get home tonight, I will at least measure the back spacing on my 8.5 and 10's. Don't have wheel calipers, so not sure I will get the other measurements for you or not....

-Doug

[Jeff Alton]

I can look up the build sheet on my kinesis if you want, but they are only 7.5/9........

Personally, I feel the O/S is not set in stone when you get this tight, and I don't feel obliged to give it out. Each car is different and with 8.5/10x17s one number will not work for everyone, and like in Bill's case may not work at all. That's where people like Greg Fordahl who works closely with Jim Fikse comes in. They know where to start with this large a wheel/tire but approach each car individually. If they can't get 8.5/10x17s to work, they will find out what will work and do that instead.

I claim nothing. I suggest nothing. I did get 10's on the back with Carrera flares on my 72. It wasn't easy and it wasn't a bolt on install. Some may feel that I should be lower, but these are 26" tires and its a street car.

18*10 65ET. slide on spacers with 54mm passenger spacer and 50mm spacer on the driver side. It didn't work the first time or the second, but with more fine tuning of lips, bolts, wires, and bolt heads it did.

Yes it has been driven now, out of state and back without burnt "primer".



Sorry about quality, I still have dial up . Country living at its best!

Here are 8.5 and 10 x 17 Fiske on an '88 Carrera with stock bodywork (and lowered to boot). Fenders not rolled:

Well thank your very much. Your spirit of community is admirable and should be emulated by everyone else.

Unfortunately the o/s is set in stone unless machining is done done. The wheel halfs are only available incrementally and the center is a fixed piece.

[Bill Verburg]

Incedentally here is the (super secret ) single reported Fikse 10x17 data
o/s +18.6

an 8 in front is an easy fit anything from +23.3 to +31.3 fits, the higher o/s giving more clearance at the lips, the lower more clearanve inboard.

An 8.5" front would need o/s at the higher end of the 8" range

The tires need to be chosen carefully as well

anything smaller than roughly 25.5x9.5 can be made to fit in the front and smaller than 25.7x11 in the back. Theses will require significant work to be done on all of the lips and inboard at the back.

Look, it's obvious you forgot where you got your 911R fitting information from..

I don't have anything against you or this community. Hell, I've contributed alot of information for over five years. I do however feel that the time and energy that Greg Fordahl and Jim Fikse spend fitting these wheels to cars is worth something, and that information is not something I as a client should just be handing out on a public forum such as this. If you disagree with me that's fine, but if you want to criticize someone your looking in the wrong direction.
