Enkei RS05RR - 18x8.5 and 18x9.5 - Will ET35 fit?

As above.

I have found THE wheels for my car and I have my heart set on them…

The sizing is:

18x8.5 front ET35
18x9.5 rear ET35

I've done the measurements and the Enkei fitment will be as follows. (This is all measured against a stock E81 M Sport 18" 261M wheel set up)

Front: 18x8.5 et35 = 24.7mm more poke (215/40 tyre will be stretched 1" more than the stock 7.5j rim)

Rear (option 2): 18x9.5 et35 = 29.7mm more poke (245/35 tyre will be stretched 1" more than the stock 8.5j rim)

In comparison to the above - for a short period of time, I had a square set up of 8j ET36 OZ Racing wheels on the car (with chunky 225/40 tyres on) and they poked 17.4mm more than the stock OEM rims upfront and 9.7mm more on the rear. The tyres were under the arches with no issues (Bilstein B12 kit fitted)

This means that the Enkei rims on the front axle would poke an extra 7.3mm over and above that set up I had...

I would have thought that the extra half inch of tyre stretch a smaller (i.e stock) 215/40 would give over a 8.5j rim should equal that out though??

In terms of the rears - the 9.5J et35 Enkei's will poke 20.1mm more than the 8j et36 OZ Racings that I had fitted on the rear - which I'm confident should work, again taking into account 1" more tyre stretch than I have currently on the stock rear rims

I'm hoping someone can confirm that these will work on the car??

Much more aggressive than I'd recommend. If you're going to stretch the tires, and do some fender modification, you might be able to drive on them, but it's not going to be an easy fit.

Yes, they will fit, but not without fender pulling and trimming on all four corners. You'll also be maxing out camber. If you're into that look, go for it. If you want OEM handling and sound, it's a no-go.

Thanks for the replies people

Here is a photo of a M135i running the RS05RR's

His front set up is 18x8.5 et35, however his rear set up is 18x9.5 et50







If the et35 fronts go on, surely the et35 rears must too?

9.5 +35 would require fender work and max negative camber...even then ehhh I don't think so. You can pull off a 9.5 +40 with a 245 on the rear, but that's about as aggressive as you can go.

It's a real shame as the above pics show that the front wheel (8.5 et35) is more flush with the arch than the rear is (9.5 et50)

You can push it a little past a 35 offset with 10 in the rear.

Whats the consensus here then folks?

As I say, the car pictured shows ET35 8.5j fronts, but ET50 rears (which still look quite tucked) the tyre sizing is 215 front and 245 rear.

Do we think that 9.5 ET35 will be too much? It would only be 15mm more poke than those pictured?

The rear rims are another inch wider, so of course the same ET35 won't work on the rear....

ET50 is about right for a 9.5 rim on the rear, ET55+ would be even better.

The thing is though, the ET50 rears (9.5j) will only poke 14.7mm more than the stock rear OEM rims, whereas the fronts at ET35 (8.5j) will be poking 24.7mm more than the OEM set up.

So in my mind, thats going to throw the aesthetics of the car out, by having a wider stance at the front, that then isn't being matched by the same stance at the rear.

Does that make sense?

I'm not afraid of rolling the arches, and dialling in some more camber if needed.

I prefer a more "euro" look on my cars anyway, this was my last MINI running 17x8 ET20 rims all round (which required an arch roll front and rear plus front camber plates and rear control arms to make them fit)

These poked 44.7mm more than the stock MINI rims in all 4 corners.

If you're looking for that kind of fit, you're right on the money. Again, though, you're not only going to be pulling the fenders, you're also going to be doing some trimming where the bumper.fender joins as well as possibly cutting out a bit of the inner fender liner. Even then, you're going to scrape when your springs compress.

Here's mine (on 19s) running 10'' rear on 245s at +35.

hey guys Im really loving these wheels and almost about to pull the trigger in getting them for my 135i.

Just to confirm everything and to make sure it will go on.

Front wheel- 18 x 8.5 ET35 with 10-12mm spacers would that work? I understand its a inch wider than stock. Tyre size Pzero 225/40/18

Rear wheel - 18 x 9 ET50 with no spacers? Tyre size 255/35/18

Im also running BC BR coliover and already have my rear guards rolled.

Im after a bit of poke with a stance look about it


Thanks
Thony

ET35 with 10-12mm spacer i.e ET25...No, you'll protrude the arches and rub badly. ET35 is absolute maximum, too much probably but you say you have arch mods, hopefully on the front anyway.

ET50 rear is perfect

If you want stance then you'll need camber plates. You can then add some reasonably sized spacers but you'll have to downsize the tyre width.

Thanks Cozy.

So if i go for ET35, will it still protrude and rub just as much?
Will I have any issue with the inside wheel/tyre rubbing on my suspension

I am chasing that wider stance look. but also want it to be driveable- I dont track me car.

Cheers

Could you remind us your wheel brand & offset. That dish is very nice in the rear

You mentioned that the guys with the M135i that you pictured had to do mods to the front arches to get Et35 to fit. Any idea what they did? I imagine a roll and pull worked and probably a 225 tyre at best, maybe 215. ET35 is going to be tight as hell so just research here first and talk to people who've done the same to find out the extent of the mods needed BUT, it'll be so flush to the arch you'll get that stanced look for sure.

The E8x and F2x suffer the same silly issue when it comes to wheels; small body over large frame so it's always tight when upsizing the wheels, hence the underwhelming looks of stock wheels.

ET50 at the rear is a pretty perfect but with a 255 tyre you will probably still scrub a little. You could add a 5mm spacer at the rear and downsize to a 245 tyre for a bit of stance and stretch.
I wouldn't want to stick ET35 on the rear if the rim is 9.5" wide. Yes ET35 can be made to fit on the front but that's only with 8" or 8.5" rims, don't forget you're adding another 1-1.5" at the back.

Sorry it wasnt me who said that. It was (R99)
Ive done my reserch on the forum looking in the Sicky Thred- OFFICIAL Wheel/Tire Fitment Thread - What has already been done to 1ers.

Seen that a few guys are running 18 x 8.5 ET35, so im guessing its doable

So I will be pulling the trigger on these wheels

Front- 18 x 8.5 et35, tyre size 215-225/40/18
Rear- 18 x 9 et50, tyre size 245-255/35/18

Thanks for your help Cozy
