Hi Guys,
just thought i'd give you guys a heads up before anyone decides to do a R33 GTST brake upgrade on a R34 GT Non turbo.
R34 GT - 14mm diameter bolt (same as GTT)
R33 GTST - 12mm diameter bolt
Whats needed to make it fit properly?
1) change uprights to R33 GTST (but that cost $$ & labour intensive)
2) redrill calipers to suit 14mm bolt (also could be costly and has potential of stuffing up and ruining the calipers, also labour intensive)
3) easiest & cheapest way is to fit a metal sleeve that reduces the hub hole from 14mm > 12mm - 10mm in length
I'm getting some made up interstate and should be getting them mid-end of this week.
if anyone is interested, pm me and i can organise a set of 4 (2 each side) to be shipped out to you.
Here is a picture of the sleeve (picture shows 30mm but what im getting is a 10mm long sleeve)
how it works & you can also see the backing plate has been modded to accomodate the larger rotor;
You can get GTT brakes and they will bolt straight up (will need to modify backing plate to accomodate the larger rotor, same issue when fitting the GTST brakes as well) but we all know how rare and expensive the GTT brakes are compared to the readily available R33 GTST brakes.
Hope this will help you R34 GT NA boys in future so you don't get the same shock that i got when i found out the bolts weren't a perfect fit
Time to start enjoying some 4 pot brakes baby
