I just quickly searched through my notes .. maybe missed some others too. There is no excuse to this crime!

Add the Motegi MR139 to your list, fits without any modification on stock suspension:

does anyone know if suspension and clearances are similar enough that all of this info will apply to a second gen car

Will those offroad tires fit at all in our wheel wells without rubbing? (+2.5" diameter) 15" were meant more for narrower winter tire fitment. And way i see, where one might benefit from offroader tire use, these cars are "not right tool for a job" due many mods needed (eg. to increase ground clearance, add extra underside/engine protection, add high travel probably rather custom suspension), by time of adding them it makes more sense to use other, better fit for purpose car to begin with. In winter, such tires of harder all season-ish compound, big rubber patches w/o small sipes in thread, without weight of heavy SUV or pickup leaning on them .. i don't expect any reasonable grip at all. In summer .. i wouldn't want to compromise sporty performance on tarmac for car that is meant to be drivers car either.

That's a pretty aggressive setup... I'd be more worried about the tire clearance rather than wheel clearance.

This person is using a 25.5" tire and clearance is probably already tight: https://www.ft86club.com/forums/show...4&postcount=86

Probably best to find the whole wheel, but who's Winter Tim?

Guess i kinda derailed the thread a tiny bit, but the 15x8+40 wheel fitment question still applies. This is for offroad or bad country road in sand or wet dirt where i don't want to sink in, not for winter/snow. Weekend warrior rallycross kinda thing, on top of frequently traveling bad country roads that get washed out regularly.

I'm running 27" diameter all terrain tires already with a 1.5" lift kit (215/65/16 on 16x7+30). After frame rail hammer mod and heat gun to the fender liner, there is no rub even at full lock. The tire size isn't the issue, especially since i'll be running it rear only where there is much more room. Its the wheel size i'm concerned about if it will conflict with any suspension by being the 1" wider than the 15x7+35. The radius on the ssr is about 1/4" larger than what i currently run, and what's shown on the pics at 27.5" diameter. If i run into issues with rubbing on the inner well, i can always put on a 15mm spacer i suppose, which will put the inner wheel rim edge more in line with the 15x7+35. I'd prefer not to have any spacers or poke though.

Slightly continuing offtopic (as i have no info on asked wheels brake clearance) are wished tires really providing more grip? Googling on gravel rally tires ( & here) show a bit smaller thread patches/more grooves. While such large empty spaces between patches imho might work better at slower speeds/at mud .. actually going at speed on gravel .. maybe different tires may work better/provide more grip?

As far as rally goes, probably only in wet mud. I will use these in non motorsports more than I will in motorsports.

I have stock brakes, not brembos.

2nd gen GR86...yes almost certainly.

2nd gen BRZ...not entirely sure if the aluminum uprights shift things at all for the tie rod. It's so close with all of these 15 inch fitments that even the slightest bit of difference could be a problem. I'll test my 15 inch Enkeis on our 2nd gen car at some point.
