SA Track Times...well Mallala then!

[Andy San]

hmm... got those adaptors organised yet?

[Katatonic]

Okay, read through the other thread but I'm still a bit confused.

Courtesy of dave:
"off AJPS for the 262mm rotor (minimum 14" wheel required)"
"User "rip it" sells adapter for 294mm rotor, or custom make yourself (15" wheel required)"

Now - bigger rotor = better (generally), is the 294mm FC rotor?

I've got 15" SSR reverse mesh - will they fit?

I've already got the FC calipers. Just need adapter and rotor now.

I just need to clarify what to do now in terms of what I buy and where from to make them fit.

[Frak]

FC = 276mm diam

[Katatonic]

What adapter would I use then? Which rotor is 294mm?

[jaz_ae86]

294 is a bit big to fit under 15". 280 is a good size like frak has.
FC rotor and caliper are not a good combo for mesh wheels (unless you want another -16mm offset both sides to take into account the rotor and spacers).
I am looking at the minicooper bracket soon out of aluminium to fit my mesh wheels, plus I hope to reduce the unsprung weight.

Just saw andy's post, will try and find some time today to make a start...

depending on the wheel style and caliper used you could get a 300mm disc inside in a 15" but it is going to be tight with 4 pots like RX7/Nissan.
The old T3 big break kit with Wilwood Dynalite calipers was 300x30 floating rotors fit in 15"s on Club4AG

But the only list a 280mm kit now.

With RX7 calipers, filfilfil had a basic cad model of a adapter to suit 280mm mini discs might still be floating around on here or another forum...
might even still have it on file.

For Mallala go a thicker rotor rather than a larger rotor. Its the mass of the rotor which increases resistance to brake fade.

Something like this:

S15 280x30mm disc, FD caliper 8mm caliper bridge spacer.

[Katatonic]

So which adapter (from who) and thicker rotor should I go with to make them fit?

[takai]

No-one makes that adaptor yet, and im certainly not going to be volunteering to do so, its not going to be a simple one.

Im just pointing out that width rather than diameter is the requirement at a high braking high frequency track like Mallala. If it was a high braking but low frequency track then width can be sacrificed for diameter to assist with those fewer high speed braking maneuvers.
If you are running 16s then you can consider running MX73 struts with either 280x30 or 298x30mm discs with a Skyline caliper pretty easily.

Edit: to be honest, if you wernt limited with wheel selection, or regs saying you cant change LCAs then i would go with something like this:


Z32 calipers, Z32 discs 280x30mm, and will squeeze under some 15s.

Thanks for the advice. AJPS have contacted me (awesome bloke) and I'll go from there.

I'm planning to supercharge after this (normal 4AGE in at the moment) but I may as well plan ahead.
