Wheel options (other than TSW?)

[jimmyducati]

geswek, you wouldnt happen to have some pictures of your car with the 45mm offset, maybe a couple shots from a 3/4 view from the front and back? Id love to see an offset that brings the tire close to the fender lip with the 255-45-20's

I too was running a staggered set on my Flex at the strip.... 18"x9" 32 offset on front with 285-40 -18 Nitto O5R DR's on TSW Interlagos 9". and 18" x 8"  40 0ffset ASA AR2's on back with Conti DW's - 255-45-18  Hooked up great when everyone else was spinning out.

However, at least on the Flex, I prefer matching wheels/tires as a DD.  Currently running Michelin Pilot Supersports on TSW Interlagos 18" x9".  Tires handle fantastic!!!!

BPD's set looks great in person... probably would do same if I had a SHO and could find the correct diameter tires in a staggered config.

I hear ya, limited time at the track wouldn't worry me but taking a 500 mile road trip or just general daily driving scares me thinking about the front being even slightly smaller than the rear. Is there a tolerance that must me maintained between the front and rear tire diameters?

[EcoBrick Bob]

I drove my Flex 120 mi each way to the track with Nitto's on, but they are almost exactly the same height as the rears were. 

I don't think you have to worry as much about AWD as the ABS system.  It just makes sense to have same diameter, even if rear tires are an inch or 2 wider.  For instance 245-45 is usually almost the same as 275-40.  You can use TireRacks specs for tires you are looking at to see if a diameter match is achievable.  For tires they don't sell, usually MFG website can give you specs.

Bob, I relied very heavily on your knowledge of tires & what not to help me arrive at my current staggered set up.

If it wasn't for your help exclusively, I'd still be trying to figure it out on my own.

TY, once again, for that assistance.

Staggered works (at least on the Flex).  My 22x9 and 22x10 setup uses 265/35-22's all around.  The extra width in the rear compensates for the approximately 15mm wider fenders back there compared with the front, based off my measurements before I had my wheels made.  Mine are +37 all around btw.

For those talking about TSW 20x8.5 wheels, I am almost 100% certain it isn't +45, it is +40 instead.  That 5mm is the difference between scraping against the strut, and not.    At least for the calculations I did for Flexi Flexes uh the Flex, my math made a 20x8.5 +40 SO close to the strut that variances in sidewall design such as a slightly oversized tire could possibly strike the strut.

I just saw a Honda Minivan with my wheels LOL.

This thread needs some pictures in it.

My ASA wheels inside fit very close to the brake calipers.  TireRack told me I might need a 3mm spacer, but it turned out to not be necessary, even when I went to new pads/rotors.

Struts and mounting brackets for them can also pose issues. On my G8's I thought it would be a cheap idea to use one of my 17" GTO take off wheel/tire for a spare.  Both had the same stock offset of 48.  However the rim of the GTO wheel hit the strut mount.  Then I tested a 17" aftermarket 40 offset wheel and it cleared just fine.  So one can have issues for various reasons.

As for TSW Nurburgrings,  I just checked the website for Ford bp wheels.

All 8.5" wide wheels are 40 or 20 offset.  Latter not workable.
All 9.0" wide wheels are 32 offset
All 9.5" wide wheels are 41 offset
20 x 10" - 40 offset
20 x 10.5" -45 offset
All 21"  45 offset
NO 22" shown as available in Nurburgring

Other TSW wheels may have different offsets for specific diameter and width. Check TSW site to be sure.  All RF (RotoForged) TSW wheels also show weight per size.

Yeah, judging by some off-the-cuff math, you'd be 1/2" (12mm) wider than my 22x10 +37 with a 20x8.5 +20.  That would definitely be pushing the envelope, but I bet it would look cool as heck if you clear.  Camber could be played with a tiny bit to get it perfect if things got tricky though.

So, to redrill wheels, all that is done is they take the existing hole and drill it out, then install an insert.  This insert is then the appropriate bolt pattern.  Probably wouldn't' work on wheels with tiny "tuner style" lug nut requirements.

Another option is the wobble nut, which is known as the PCD variation lugnut.  Some brands have even passed TUV cert, and are considered "safe".  It is another option as long as you use good centric rings. 


edit:  I lifted this off the G35 guys

  the magenta is 112, and blue is 114.3.  Helps visualize a bit.

I looked at my Flex rear wheels.  The top of the rim is about 1/2" inside the top of the outside fender lip.  So 20 offset in 8.5" would work on back..

Wanted to add to this, now that I've got my alignment done and the rears cambered properly, the wheel I've chosen in the rear 22x10 +37 is lip flush to the wheel well at least at the front of the wheel wells.  Since the Flex narrows from rear to front, it is hard to judge and therefore flush up because the wheel and the wheel well are not parallel.  The wheel is more or less straight but the wheel well is angled in a tiny bit.  Makes the rear of the wheel wells sink the wheel in, and the front poke them out.  I think my +37 is a compromise between the two, with the front and rear showing a tiny bit of lip at the front of the wheel wells, and tucking a bit at the rear of them.

Given that, I think a +20 8.5" setup might poke a tiny bit, but only on the tire.  I was using 255/45-20's there but that's a normal size for both the SHO and the Flex.  Just looking at this link,

You can see it better.  I think it would work.  It appears a 20x10 +40 (rear fitment for TSW Nur for a couple folks here) is basically identical in poke compared to a 20x8.5 +20.  Very interesting how that works out!
