Bola CSR 18x9 at ET45 over M140i Rear Brake Calipers?

Post by ryujinmaru » Thu Jun 14, 2018 3:42 pm

Hi there, looking for some advice regarding fitment, as per the subject title.

Does anyone have or had the Bola CSRs in 18x9 ET45 configuration as their rears on their M135i/M140i?

I'm worried they may not clear the brake calipers and don't want to use spacers, which would exacerbate the already borderline poke of that set-up.

If there is no clear answer, I may look more into the Bola B6 for the partial convexity. Thanks.

Try using "SEARCH" in quick links.

Type in "BOLA" and select this sub-forum then see what comes up...

Thanks for the tip, but I had already searched the forums before I posted.

I had already seen that Duckson has the 8J version at ET40 all round, but that does not answer my question.
A certain Jimmer even had the 9J in ET42 on his M135i, but as he no longer seems to have a user account anymore, I could not ask him whether he had another few mm to play with between brake caliper and rotors.

Why not email the Bola people yourself, I believe they are a British firm.

The website was down, but I did ask them via Facebook messenger before I posted. Wanted to see if there was someone with first-hand experience for a quick answer.

Bola did get in touch a day or so later and said they had sold 18x9 ET42s and also ET45s to M135i/M140i owners "without problem". I assume without spacers, but they did not seem to want to commit. Understandable, as they can't 100% know unless they tried to fit themselves. It seems it should work anyway.

However, having measured to see what the extra poke would look like on the rear, I think I'm going with the ever-popular square 18x8 ET40 set-up instead.

Yes I believe the extra poke is about 12mm or so and will do no harm at all unless you are running very wide tyres on a significantly lowered suspension set up.
