Sorry but this is a very urgent question. I am in the Classic Adelaide Targa tarmac rally next week and have just discovered a serious issue.

I have R33 GTR turbo rear calipers on the rear of my car. The caliper body is hitting on the rim without me realising (wheels put on by others whilst on a dolly so nobody realised!!). How much can I grind off the edge of the caliper body in the area shown in the attached pic (ie the edge of that roundish bit)? I really need to remove 3-4 mm.

Has anybody done this or pulled one apart and knows the answer?

Hi mate, a much easier answer would be adding a 5mm slip on spacer, unless your wheel nuts will be too short.

I've taken 2mm off a caliper before for a similar problem and got away with it, but 3-4 would be really pushing your luck unless someone has done it before....afterall do you have a spare if you stuff this one?

BTW....good luck!

Buy a spare and see how much material you can remove before hitting the fluid. I would guess the calliper is pretty thick at that point, you should be fine. It is only fluid pressure you would need to worry about imo as it isn't near the mounting point. That said, Duncan's idea is the better option.

      Clutch hydraulics are also all good, looks like a brand new slave cylinder and everything bled up well. No idea what the actual clutch is, and I don't intend to pull the box off on the floor to find out, so unless we have trouble on the dyno or at shakedown that will remain a mystery for the new owner

      Front brakes are G4 8 pot calipers over 330mm discs with braided lines. Everything looks good, pretty sure these are off my old 350. Pads are brand new and judging from gold colour are Winmax which is what I also run on my race car, Neil and I both sourced brake stuff from Matty at Racebrakes Sydney who really knows his stuff Everything has bled up nicely with all new Motul RBF600 fluid, there were 2 loose hard line connections and the calipers were new on the car so I ended up doing it 3 times but it is perfect now

      So, starting with the rear brakes. They look like standard R33 GTST, and will need new pads shortly (less than 5mm material, probably only 1 day left). The slotted discs (probably DBA) are near new at 18.01mm and the lines are braided

      Cleaning my wheels 😍

      By The Bogan · Posted

      I clean my wheels every time I wash the car, I also clean the barrels, the only product I use on the wheels is truck wash and a pressure washer, followed by (inset your chosen name brand) wash and wax, time per wheel is probably 2 minutes total, cleaning the barrels is easy with one of these microfibre thingies on a stick from Sabco, they're also great for getting in between the front guards and body, and tight spots in the engine bay

      An updated post here. Sounds to me like there's definitely a bit of sketchiness here.  Old mate with 10 rusting Torana's in the front yard might be more who they're focussed on. (For right or wrong).
