Hi guys,

I'm interested in buying a set of BBS RX for my 1990 E30 sedan. The spec is 17x8 ET10. Would this fit my car w/o having to go the widebody route? My fenders have been completely rolled and folded..

Thanks

Looking at a set of Kensis Kt1 wheels was wondering if they'll fit my late model vert can someone please confirm if I have this dialed in correct?

Front 17x8.5 et35 I'll need 20mm spacers mounted on 205/40/17 tires
Rear 17x10 et30 I'll need 10mm or 15mm spacers mounted on 215/40/17 tires

Any other tire sizes you'd recommend to reduce lots of tire stretch but still able to clear?

By the way car is on its way to getting fitted with airbags and camber adjustment plates

I have a set of 16” oz futuras that im going to refinish with new barrels and lips. Im going to step them up to 17”. I want to go as wide as possible while replicating the same flush look I had with my 17” style 5s with 20mm adapters. How should I go about calculating this? I found a chart online that if I read correctly states I can do 4.5” barrel and 3” lip if i kept the width at 8” and et at 0 same as style 5 but not sure if thats accurate. I get lost once I try to figure out a wider fitment.

Looking for some confirmation on tire sizes / fitment:

I have a set of 16" Style 5s from a e38 7 series that I wanted to put on my e30 with (blox?) 18mm 5 lug adapters.
Was planning on buying 205/45 R16 tires. Car suspension is all stock, but hoping to move to a Bilstein struts with H&R shocks here shortly.

Will this fit without any additional work and not rub?

Thanks

What’s up Staszek, you helped me about 10 years ago to get the right fitment for my C5 salad shooters and I’ve come for your help again!

I’ve recently purchased some ACS II monoblocks I want to fit on my car. I’m using Nasieg’s 5 lug kit so an e36 front bearing and I’ll be using the z4 rear hub to get me to five lug. The wheel specs are 17x8 et38 and they currently have a 225/45/17 installed. I want to fit a larger tire for when I do my engine swap but I’m not sure what size spacer to use or how big of a tire I can use. I’m thinking 235 or 245/40 though. I don’t want to be super stanced ( the car is currently on a H&R sport cup kit ) so I don’t mind if they aren’t flush. I’m more about tire on the ground.

Thank you!

Let me think about that one. Haha I gave advice 10 years ago and it worked lol :)

Nice, thank you for your advice. I haven't even thought of adapters yet, was just hoping the wheels would fit. Good news though...

Are these open wheels or do the bolts have a cover? If they are covered you could drill and fill then get 10mm spacers and you would get a perfect fit.

Hi, I'm really interested in buying a set of racing dynamic wheels. The following is a description of the size...Size = 16x8, offset 33mm
Lug spacing is 5 on 120mm.
Center bore = 72.56mm

Do you think these will fit if I get a set of 5x120 to 4x100 adapters? Do you think I'll need to roll the fenders? I will be going with toyos 225x45x16s. I have h&r race springs. Thanks

What MM are the adapters, most of them are 20 which would put you at a 13 offset. With 225s you will probably have to roll, you will also have a decent amount of poke (wheels outside the fenders).

For reference, I have 16x8 et23 and it fits perfect with 225/45R16, I could actually go out another MM or 2 if I wanted but I think its right where i want it right now in the front, the rear I will probably bump out a bit.

Anyone have pics of 225/40/17 up front and 245/40/17 in rear or 225/45/17 and 2245/45/17?

Oh wheel fitment masters out there, I need some help.

I'm changing up my set up a little bit. I currently have 16x8.5 ET 8 wheels with 205/45 tires. I'm going to go to a 16x8.5 et 20 setup. I'm imagining that it would fit with the 205/45 tires. However, would it be possible to run a 205/50 tire with the new et 20 setup? Would I need spacers to clear the front struts? The fenders are rolled/pulled already, and the car sits on H&R/Bilstein sports.

Thanks in advance for any help!

Does anyone have any pictures for et13 17x8.5?

Hello! I recently aquired a set of 17x8.5 ac Schnitzer type 1 monoblock et13 rims. I am planning to use them with 20mm 5x120 adapters. Question is, what tyre size i can use? Im not really a fan of stretching. I have an early pre coupe. What are the options?

You would be at a -7 offset, unless you doing major fendor mods that will not fit at all.

Won't fit. Best option that i can think of is to sell the wheels.
