Skyline Brakes on AE86, will they fit in 15 rims?

[AJPS]

100% agree

Caliper overhang:


Thats with the BA Falcon rotor, which is 10mm deeper. Add 10mm to the overhang for the stock Nissan setup.

I'm going to go against what everybody else here has said [Edit: Except AJPS], and say that I couldn't agree more. (Although your theory based around the use of Bendix Ultimates kinda blurs the credibility of what you've said...)

My favorite example of proving to people that you don't always need larger hardware (read: more unsprung weight) is Evo 4-9 rally cars, with 550 odd nm, anti-lag, brutal acceleration, and ALOT more weight than any AE86 is EVER going to way, don't exactly struggle with twin piston single sided opposed piston front calipers working ridiculously small 276x24mm rotors when used with the correct pad compound.

Another example is recently a very reputable workshop tested the twin pistons calipers that come on the Liberty GT, versus the 4 piston sumitomo calipers that come on the WRX (The exact same Skyline/300ZX calipers every here is talking about) and the twin piston, single sided sliding calipers on the GT out performed the 4 piston jobies...

So apparently, unlike alot of other people here, I certainly don't subscribe to the needing-the-most-pistons-possible theory when trying to get the most out of your brakes.

Only problem with the single sided calipers is they spread open under hard braking and you end up with wedged pads and a shit pedal feel because once it has wedged the pads it will spread them every time once you stand on them and because they are worn so unevenly you need to keep replacing the pads to get your pedal feel back.

The other thing you interstate guys don't have is Mallala to drive on - worst track in Australia for brakes, when i went to eastern creek earlier in the year i could have got away with the standard calipers without a problem, but you cook them in 3 laps here

As far as rim fitments for these r32/3 setups, i just had a chat with Retro Wheels (NSW) who bought the licence off Simmons to make all their 15" rims, they are able to custom make up any size offset rim and extend the center boss to give you the caliper clearance you need (up to 40mm i think), i figure this is more than enough to fit over skyline brakes (the guy i spoke to said that he had used GTR brakes on his sons celica and made the rims to fit over that), i also asked how much it is to make a custom design center and it was a fair price if a few people wanted to get together to make up some JDM style rims that where accessible in Australia, just a thought.

With The 15 x 10 superlite it has a decent spacing, but the issue with them and the caliper is not the spokes, it's the center mounting disc. That's what the caliper hits.

i never said bendix ultimate were good, they are shit, that was the whole point on what i was trying to say

[fantapants]

yeah i found this with my 296 rotors.... fit inside my 15's and 16s, but doesnt clear the mounting face on eaither

296mm discs and wilwood caliper inside a 15" rim


Ill slap one of my spare R32 calipers in for giggles, but i doubt it will fit. The wheels are Simmons V4s, not exactly the best for caliper clearance.

[Dongaz]

What is the part number on that wilwood caliper?
