Who wants to see Wilwood Brakes vs. AP Racing Brakes ( Sprint Kit ) - Page 7 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Dezoris · 12-26-2013, 05:03 PM

AP Racing Sprint is going to be the best bet for track sessions under 2 hours at a time.
If you are running over 6 hours track time per day endurance maybe better.

Most all of the track guys on here run the Sprint version and don't require any changes to rear brakes besides pads.

One thing I'll add about the Wilwood kit that I've experienced on the track, they increase rear bias quite a bit. I thought it was my stock suspension I ran on the first track day I used the wilwoods on; but I've since tried used rsr coilovers, and more agressive front pads (poly d's then poly h's) and still too much rear bias.

And I only have the shitty non US spec rear brakes, with TRD pads (that are only marginally more agressive than stock.)

So the only thing I'm left with doing is installing a proportioning valve to reduce rear bias.

Bit disappoint TBH. When they say they work with stock rears, I expected they meant it maintained similar bias.

Has anyone ran the sprint kit in the winter with snow? Did I read that it was not recommended?

diss7 · 01-09-2014, 12:18 AM

I've sold my Wilwood kit, and am planning on getting one of the AP kits. Hope to have a review up of the differences in the next month or two.

Clean them and they'll be fine, but since they aren't painted, etc they aren't as ideal as the OEM stuff in the winter in terms of corrosion resistance.

You could swap them between seasons, kind of a pain in the arse but that's what I would do if I had to deal with salt/etc.

feldy · 01-09-2014, 12:42 AM

What about the pad it self?

CSG Mike · 01-09-2014, 01:23 AM

@feldy: the pad itself will be fine; get something appropriate for your application.

The caliper itself is not painted, and will corrode with salt, etc...

JRitt · 01-09-2014, 09:39 AM

We don't typically recommend running our kits in snow and ice, but some people do it anyway without issues.

Does anybody know if the dba rotors are a possible replacements for the sprint kits?

No. They aren't the right size, don't have the right number of mounting ears (based on pics). They aren't cheaper either (at least based on the set of WRX replacement rings I saw on eBay based on US pricing).

Then there are basically no other options? I just feel that I would like to try other rotors just to test it out.

If you mean other rotor options that bolt to the Essex hat, there probably is. I haven't searched but it's a production AP Racing rotor ring so the measurements are available you just have to find something that matches.

Here's the manufacturing drawing for the rotor ring included with the Sprint kit: http://www.essexparts.com/media/down...62-104~5ga.pdf

35-45 offset are just right for a 17x9 wheel on our cars, IMO.

I have a question. I have this exact Wilwood kit I bought off a guy locally but I want to upgrade the 12.88" rotors to the larger 14" ones because the 12.88" ones look to small behind a 19" wheel. Can I use the same caliper and bracket and upgrade rotor size?

liquidsky44 · 02-24-2014, 12:24 PM

I have a question. When do you guys change out the ap sprint kit rotors? Currently I'm left with 28mm and still contemplating on should I change it soon.
