SA Track Times...well Mallala then!

[Frak]

you may find 9 laps of sub 1:20 different, some of the fast IPRA boys are changing pads etc every meet!

[jaz_ae86]

Sub 1:20 very different, VERY DIFFERENT.
** Remembers to go check pads and rotors **

but the same thing remains: JDM AE86 brakes will never be sufficient, even doing 1:30's for 9 laps.

[Frak]

oh come on, you don't think those 234mm diam rotors with flexi single piston calipers won't do it

[jaz_ae86]

Jdm = pathetic

fit some VL turbo brakes bro and a 9" detroit locker with leaf spings

That's why sprints are good, you only do 3 laps at a time so you don't cook anything but tyres barely get to temp. In the longer IPRA rounds 10-12 laps you see who's tyres are shot or buggered brakes by the end.

Hey Frak, bit off topic but what was that regularity/enduro thing you did many years ago with 3 drivers per car?

[Frak]

6 hour! which I expect in the future we may do

I was actaully talking to my good mate Daniel R the other day about it, he and his mates always enter a number of datto 1600's.

jaz how do your FC brakes hold up?

What have you done about the rear? Still JDM or...?

[Frak]

FC brakes are good, but if you are going to do this conversion try and track down some FD calipers, they are lighter and more rigid(on the series 6 they went to a different casting method, it was a 'squeeze casting' method, which made the caliper stronger but also lighter), series 6 suit a 22mm thick rotor, so useful for most common conversions. ALL FC and series 6 FD calipers have equal size pistons.

I put FD series 7 on my 86, the reason being, staggered pistons, this will stop the pads from tapering as they wear. Again the series 7 suit a 22mm thick rotor UNLESS it's an Aussie SP RX7 then it had JDM RZ spec rotors and calipers, which was a 312 x 32mm rotor and a caliper with staggered pistons.

Probably one of the best mods I ever did to my 86 was to upgrade the rotors and calipers (I use a 282 x 22mm rotor) the brakes are VERY powerful!

[Katatonic]

Thanks for the info.

I've got two sets of FC calipers coming in and I'll mess with them first.

If I feel like playing a bit more I'll take a look at FD ones. I just wasn't 100% sure if they'd fit. I'll be using AJPS brackets so I'm assuming they will.

[jaz_ae86]

Big difference using little civic rotors over FC rotors. For the same reason you cannot get JDM brakes to work, you really need larger rotor dimensions to make it work/last. When I start running out of brakes, then I will look at bigger rotors like Frak.

I run the full FC rotor and caliper set up. details are in this thread:


I run a t18 drum diff converted to AE86 disc brakes and calipers. Have recently gone 15/16 master and willwood bias adjuster to try and get the rear working better.
