SIZE AND SPECIFICATIONS: The front wheels are 17x9 with a 5.95" backspace(+24mm offset) and the rear are 17x10.5 with a +27mm offset. The lug pattern is 5x4.5 (114.3mm).

will these work on an FC I know I will have to go wide body but will these clear the 4 piston calipers or will spacers be needed? oh stance coilovers also

Thanks
Tony

these are the rims there going on a white fc

I can get you stance just let me know.

The fronts won't work with coilovers.

10.5 +27 will clear on inside but not outside.

There's no way to determine brake clearance until you test it. BUT in all reality it shouldn't be any problem clearing the Stock FC 4pist calipers.

FYI, safest bet is a 9" +15 offset to clear coilovers.

You will need to widebody or pull fender.

 

wouldnt the coilovers give more clearance over stock suspension? my 18x9 with +24 cleared the front and only needed the lip rolled on the outside. it cleared the inside strut by like 5-10mm.

 

Nope, not on macpherson strut. You lose backspacing unless you use an OEM type strut and Ground Controls.

 

What ARD said, hes the MASTER of fitmit. Contrary to popular belief, coilovers on the FC give you NO addtional clearance, infact in most cases less clearance unless its a stock strut with the Ground Control coil retro fit kit. You can gain some clearance with a coil over if you use a short spring, but when its unloaded it flops around (and if you use a tender spring to fix the flop, then you loose the extra clearance).

I just test fit my 16x8 +30 up front with 245/45 and JIC FLT-A2 coilovers. It fits and RA1 aren't the narrowest tires in section width.

I checked to make sure that if the rim was 1/2 taller (17") it would still clear the coilover spring and perch as I am looking at 17s. It would clear.

9" +24 would be 2mm closer to spring and perch and should JUST clear.

24mm further out though which will require a big fender roll/pull to fit a 245 under it or 30mm wider fenders.

I was looking at those rims on ebay as well. How heavy are they though? Are they straight after welding the rear wider?

If you ever do have to make some room for a coilover and a rim there is a trick to it.

You can make the upper strut mount to hub carrier hole larger and offset the carrier away from the strut. You can use an eccentric crash bolt or better make a bolt in countersunk offset insert as some high end coilovers come with already.

You do lose some of the maximum negative camber adjustment this way however and change the scrub radius (but in the right direction if going with a lower offset as you will have to for wide rim/tire).

A taller wheel/tire combo will also help decrease the scrub radius of a lower offset combo.

This would come in handy if you want a 275/40-17 up front on a 9.5 +15 rim and a 30mm wider fender (REALLY close fit with lots of negative camber). Both offsetting the hub carrier and the larger diameter tire would help bring the steering axis back out closer to intersecting the middle of the contact patch.

But I swear I haven't been thinking about this much....

 

I'm using:

Front - 17x9 +22 RPF1 with 225/45/R17
Rear - 17x10 +18 RPF1 with 275/40/R17

Zeal V6 coilovers. Clears TII 4piston calipers. Had to roll/pull the front about 5mm and 15mm in the rear. Negative 1.75 camber in the front and negative 1.25 camber in the rear.

 

I've mentioned this trick over and over and over and even disscussed the whole scrub radius. Well, I disscussed it to my self I suppose even though I posted several times NO ONE seemed to read a damn thing I wrote as there were no replies to it or even an acknowledgement that I shared my way of running wider tires without fender rolling or screwing up your scrub radius wiht low offsets. I'm glad someone paid attention, or if you didn't read any of my post, I'm glad I'm not the only one to figure this out on their own (or perhaps heard of it through some other source?).

I'm running 18X8 38 offset and a known to have WIDE section widths BFG KDW2 235/40/18 front and 18X9.5 35 offset 265/35/18 rear with NO fitmit issues, no fender rolling etc. And the car has good scrub radius measurements and handles GREAT even with the staggered wheel set up. I run TEIN Flex coilovers, all poly bushings, rear steer elim. for now stock sway bars and I have custom set up roll center correctors (droped the lower fron A -arms). I'm using the TEIN upper pillow mounts for camber adjustment, I also slotted the upper strut mounts and have custom upper strut brace with slots also for castor adjustment along with cam/eccentric bolts in the upper strut mount were it bolts to the hub for scrub radius adjustment and tire clearancing. The rear has both the single camber adjuster and both side adjusters. I also made the rear toe links adjustable via custom rod and HEIM joints for adjusting toe. I used the front trailing arms toe adjuster for maximising roll center (adjust them to full up position and use the rear toe rods for adjusting actual toe settings). WOW I just gave away another trick of mine, lets see how many paid attention this time.

Too bad most of the people posting and reading in here have no clue what the **** you said...

True.......

 

nice to share the info though.

its a great idea to keep scrub radius in check, although I dont feel like scrub radius is an issue until you get VERY far from stock track width setups... 235's up front seemed perfect to me without any scrub radius modifications.

 

I just put it together in my head last night, but I am sure this trick has been used a long time. I had seen pics of aftermarket coilovers with eccentric top carrier bolts and then read on the web about larger diameter helping scrub radius last night searching for a offet calculator.

Your set-up sounds very nice RacerXtreme7!

Owen, I have driven a car w/ 17x9 +15 255 wide tire and it was awsome on the track, but a bit scary on the road. I can't imagine driving at high speed and having the car dart back and forth over slight road imperfections like it does at freeway speeds.

 

Thanks you all. this was verry helpful

Tony

 

NyToy had that setup and it was beautiful on the street I thought, he did have power steering and a fast ratio rack as well, about as crazy as you can get for tramming/tracking and it wasnt bad at all IMHO.

I have 285's up front and while my car does track a bit it sure isnt darty although I do drive with a heavy grip on the steering wheel I suppose. I have been surprised at times with the car wanting to go somewhere else in a hurry when I wasnt gripping the wheel properly and nobody likes it when the car lane changes for you out of nowhere, wtf?!?!

oh man I think a 17x9 +15 255 front and 17x10 +25 255 rear is one hell of a good setup for a FC to have a combo of grip and nimble feel without any of the heavy feel or steering from even wider tires.
