Hey guys,

an anyone help me out with finding twin spot callipers for a GQ? Will they bolt straight in? And will a 15inch rim fit with these callipers?

Thanks in advance

I assume you want twin spot fronts ?? I have been told by a mate that runs a dedicated patrol wreckers that gu calipers won't bolt on . Maybe the whole swivel hub assembly will?

later efi model gq's came with twin piston calipers

i just did this, found that you need to get the backing plate with the calipers, i just hacked mine up as i did not get backing plates. also the caliper bolts rub on the disk when fully tighted so i had to chuck an extra washer in there to pull it back a few mm's. apart from that every bolts on..... gl findin a set of calipers for a good price tho..

Does this conversion make a huge improvement over the single piston caliper to warrant the expense?

Are the rotors larger when the GQ's came out with the twin piston calipers?

i think they a marginly thicker and bigger in diameter, my front brakes where shot and pull up much bettter now, makes a difference when towing aswell.

Do 15" rims still fit on?

yep

Can you use the same master cylinder or do you need to chang it too?

no need to change the master cyl
