Now i usually trust my dealer but I just want to make sure nobody can prove him wrong on this.

I have the JCW 18 inches R105 wheels and apparently you cannot fit a JCW big brakes kit with those wheels, the inner dimension of the wheel being too small. I find it kinda hard to believe in a 18 inches wheel...

Can anybody confirm or destroy this theory?????

NOTE: the picture below is of course the R105 wheel with the standard JCW kit, not 4 pot big brakes kit

 

The dealer is right. You cannot put the new big brake JCW kit on a R105 without adding at least a 5mm spacer. As long as a spacer is installed there should be no problems with fitting. This install is on my wait list and have 15mm spacers already installed.

Cheers!

 

Well you make my day Tilen! I was thinking about H&R 15mm spacers since i lowered 2 weeks ago, now i will have an even better reason to install those spacers!!!! Thanks for that precious info...

 

Check the clearance before going with the 15mm, I think 10mm would be wiser on R105 (R53), I had to trim the arches a bit. Which tyers do you have on? 215-35 or 205-40? Post pics if you can...
