After applying some aluminum tape around the sensor and inside of the rear bumper it is now very reliable no matter what wheels I have in the car.

Is there a write up on this someplace? Thanks!

Just got some Fastwheels FC04s. 17x8 et45 with 235/45r17 General G-Max RS tires. This combo comes in at 39.4 lbs, 6.7 lbs lighter than OEM.

WARNING: this is an extremely close fit and does require a small spacer. With no spacer the tire just touches the strut, so I machined some 2mm spacers and now have exactly 2mm clearance to the strut. With a 225 or OEM 215 width tire everything should clear just fine with no spacers. Also, different brands and models have different section widths for the same size so some 235s may be fine, others marginal (like the G-Max RS) and others will definitely rub (Hankook RS4).

Car looks great! You are making me a bit nervous because I am planning on running 235/45/17s also, but the wheel has an offset of 40, so I think I'm good...hopefully, lol!

You should be fine with a 40 offset. My wheels only came in 35 or 45 so that's why it got tricky.

Got them on the day I took delivery - so far so good - 41 pounds for the summer set. TSW Paddocks - loving the Falken summer tires too! yes I know the blues don't match!

ZBrown I am looking at 17x8 wheels and have a follow-up question on your fitment. The gap between the sidewall and the strut is very close at 2mm. Under cornering, tires will move a LOT relative to the wheel, sometimes an incredible amount depending on cornering forces and tire construction. I race cars and even with 35 series tires they move enough to cause rubbing when there is significant static clearance. Have you checked to see if you have any contact between the sidewall and the strut?

With a 17x8 I am considering whether it would be possible to move the wheel farther out by using thicker spacers than what you mentioned. However, without pulling the fenders, then clearance with the tires and fenders could be an issue. Have you seen any rubbing in the outward direction?

Yet another way would be to go to a narrower tire and stretch the sidewalls a bit, causing the tire to taper inward from the wheel to the tread. This is a trick commonly used in the road racing world to stiffen the sidewall of the tire for better feedback. That inward taper would also help with sidewall clearance.

Thanks

The bottom of the tire sure can move around a lot under cornering, but the top is not nearly as bad. Add to that the highest loaded tires (outside) are flexing the wheel to increase clearance at the top. After lots of hard street driving, and two autocrosses there is no tire-strut contact whatsoever with only 2mm clearance. I have also never experienced any rubbing of the fender either.

My wheels are 17x8 et45 with a 2mm spacer (so effectively et43). The wheel studs are pretty short so I personally wouldn't run more than a 3mm spacer without installing longer ones. Another downside to running the tire so close to the strut is if you want more camber you would have to use camber plates as opposed to eccentric strut bolts. A 40mm offset may be more ideal if you want to increase the camber, run 245 tires, or are concerned about clearance. However, I know some of the people running 245 tires on an 18x8 et40 have reported a slight rub on the fender while at hard lock and going over a bump.

Running a narrower tire would help the clearance as well. The stock 215/50r17 tires will clear the struts on my wheels without any spacers at all.

I'm down to two choices (both 16s) for my winter setup. Vehicle is slate gray. Which do you like?

1) Sport Edition A10:

2) Sonic wheel:

I am sending you a private message.

 

[Littlecars]

My very heavy stock Bolt wheels and heavy goo tires (which, 71 miles into ownership, failed to seal, yet it was a Discount Tire patchable puncture) - have been replaced!! 8.5 lbs per corner saved, in unsprung rotating weight - 34 lbs total!
Wheels: Maxxim Winners, $125 each. Pirelli P7 tires helped in the weight department as well. Here's Eve... (the white robot from Wall-E) see if you like the look.

Tom - those wheels look great on white! Sporty and light.

 

[dasto]

The wheels that I have listed in the Marketplace weigh 16 lbs each. Super lightweight.

 

[lucycan]

Any opinions on my choices? See post #350 above. Thanks!

I don't know which one will work better in snow, but I like the looks of the Sonic wheel. Just a personal preference.

 

[lucycan]

I went a different direction

 

[Shona]

Can anyone speak to these wheels I'm considering buying for winter? I'm not exactly sure how the offset number gets factored into the equation. What I'm looking for is a 16" alloy wheel to put dedicated winter tires on. Reducing weight is also a goal.

Option #1 because it will be easier to clean the snow out of the wheel wells, I think .

Ooops I meant that for Lucycan.
