The driver's side rear caliper failed on my 2009 X coupe, so I using that as impetus to upgrade to Akebono calipers all around. I'm guessing it was heat damage from when I cracked a rotor at Watkins Glen two years ago...

I know this swap has been done many times before, and I'm sure this question has been asked, but my forum searching skills have failed me.

What size spacers will I need to clear the stock 18" wheels (which I use for winters)? I have 19" TSWs on now, and the 18s are in storage, so measuring with a template would be a pain.

Will I need spacers on all 4 corners, or just the fronts? Is there any issue with stud length?

Thanks!

 

25mm all around. Ive been running it for years.

 

Is that the minimum you can run? That sounds kind of high

 

Depends on how low you are and what look you're going for. People do 20 in the front, 25 in the back. 20 all around

 

25mm seems crazily thick, that's about an inch. I just want to clear the calipers with my winter tires. My car isn't lowered and I'm not worried about it being 'flush'.

 

Might check this reply from Johhny, he has a coupe w/ 18s way back when

im actually trying to do the same exact thing. i have a set of 18s inch wheels from a vert powdercoated gloss black. it appears from blnewt's link 15mm is the way to go for front wheels

 

If you have the wheels in hand I'd run the templates just to be sure, some OEM 18s will clear as-is.

Thanks for link. Quality 15mm spacers appear to be out of stock on Amazon. I'll have to find them somewhere else or just wait until it's closer to winter and check again.

I would like to check the wheels with the templates, but it's not convenient to get at them right now.

 

If you have the traditional journey 18" wheels as seen below.. 10mm spacers up front will clear Akebono's. I know from first hand experience as I run these wheels with Michelin X-ice3's in the winter. (10mm H&R's on extended lug bolts). It is within a millimeter or 2 of clearance, if that..but it clears. Problem free all last winter.

I run 20mm in the back, but not for clearance sake (not sure if they're even needed, I don't believe so), just to keep from looking sunken in throughout the winter and with the fronts pushed out already. I am lowered on Swift and Koni's, thus the sunken in look on stock offsets is a greater aesthetic offense that had to be addressed along w/ the clearance up front.
