Check the Enkei Raijin, nice looking good quality wheels w/ a lot of sizing options

Avant Garde also has some wheels like the M580 or the M510.

Hey guys just a question as I am confused

a 255/35/20 tire on a 20X10.5 offset = 30 rim

How stretched will this be? Confused here just trying to get a visual or measurable definition.

I assume you meant +30 offset. A 255 on a 10.5 will be quite stretched but is very common. Your sidewalls instead of going straight up w/ a standard mount will angle out from the tread block to the wheels edge, this also leaves the wheels edge unprotected by any tire protection rib. Here's a pic of a 255 on a 18x10.5

thank you. What would be a tire size to run so that the outer rim will not stick out ?

If you are planning on running that 10.5 +30 offset on a sedan that's about the widest tire you can run without running extra camber. If you are in a coupe you could run a 275 width tire and this would offer a more standard mount w/ better wheel protection.

But that little rib of rubber offers just minimal protection, better than nothing, but the best thing to do is avoid curbs at all costs. I don't park at the end of the line where there's curbs, I go a bit wider around curbed corners, etc and the wife is also following suit

Thanks Brad! I came across the Enkei TY5 in 8.5 +25. Based on the wheel calculator that should be pretty similar fitment to the 9 +30 right?

I'm seeing most of the Enkei are cast wheels vs TSW rotary forged. The TSW shows about 4lbs lighter than the Enkei. Is there a reason people avoid TSW?

Thanks - Matt

TSW has been around quite a while and has a decent reputation, there have been cases of them being a "softer" wheel that could be more prone to bending. I wouldn't cross them off your list, for the price they aren't a bad choice. Enkei, being a Japan sourced wheel tends to be a notch up on the quality scale vs. most other wheels at their price point that aren't made in Japan.
Enkei also has a rotary forged line (aka as flow forming and a couple other terms), these are lighter and stronger than traditional cell castings, but it's still not a forged wheel, just an improved casting process.
Another advantage to that process is the spokes don't need to be as thick as regular cell cast so it's easier to make wheels that clear big brakes

And yes, an 8.5 +25 will be just about identical at the fender as a 9 +30.

So I'm looking at the same wheels as Waste86:

https://www.myg37.com/forums/build-t...s-fi-tt-3.html

the WedSport SA-15R in 19x9.5 front and 10.5 rear. I'm lowered about .5" in the rear but stock height or higher in front. This is limited by the adjustment range on my tein coils. Proposed tire sizes are:
275/35/19 front
305/30/19 rear

The question I have is with the offsets. I'm definitely going with the +45 rear. Waste86 has +35 front but I've seen others with +45 front

Ape Factory:

RadioFlyer:
https://www.myg37.com/forums/wheels-...ml#post4115767

I'm leaning towards the +45 since it has less scrub radius:
https://www.wheel-size.com/calc/?whe...cl=30mm&sr=0mm

Wheel specs just in case:
http://nebula.wsimg.com/dda2ee6e5209...&alloworigin=1

Is there any reason to go +35? Which one will fit better in general?

Nice wheel choice
Are you not wanting to go any lower on your Tein coils? If you're only dropping .5" in back and basically stock height in front you'll be outside their optimal height settings which may result in compromised performance and possibly shortened damper life (not sure on that one).

At any rate, that's a lot of tire in front so you may want that +45, only issue I could see is you may have real tight clearance to the inside (the upper section of the steering knuckle) so you may have to run a bit narrower tire there. Rear should be ok, the inside clearance may come into play there too on a +45 w/ a 305 tire, I've read that there's about a finger clearance there w/ those specs, so that should be enough

Should be a really nice track oriented fitment. I can double check in with Weds Wheels. I'm also checking their inventory and it seems like they're down to one last set but in a mismatching finish. This is for coupe?

No more lowering, I live in a city. I guess I'll stick with the +45s then and maybe have to go narrower tire in the front if it comes to that.

I've had TSW wheels on most of my euros and have had zero issues with them. Mine all were strong and I don't baby my cars, I don't dog them either, but I do drive them and enjoy them. I am careful with curbs, train tracks, etc etc. I'm actually considering a set for my G
