Hi guys,

after consultation to day with centerline suspention i have being advised not to go with my planned brake set up (r33 gts-t calipers f and r plus slotted disc) and go for a full race set up (manly bigger disc).

just wondering what you guys are useing, were u got them and how much you payed.

the car is a 89 r32 gts 4dr and im thinking of 6 pot front 4 pot rear set up with brake bias adj

Still, it is going to be an NA car, i expect lightend? So you will have about 200hp at the wheels if you are lucky. So i would suggest some R34 GTT brakes will work fine. Be careful using the term race car....i suspect your total budget will be doubled by the cost of race braks alone. Even if you go for premium stret brakes i suspect the 6-10k is more then tiy should spend considering the lap times the car will be doing

Endless calipers? Have you looked at the price of pads and rotors?

R34 GTT calipers are 4 pot and run a 310mm rotor, only catch is you hae to drill out your hub to bolt up the caliper. Shoudl be plenty of rotor for your GTS, or even stiuck with teh std caliper, grab some DBA 5000 GTR 324mm rotors and grab some adaptors tat allow you to run the rotor. Much more in line with the straighline performance and weight the car will have

what do you mean by drill out hub are you refering to redrill from a 4 stud to 5 stud? or the mounting bolt holes are of the wrong diamiter.

It's more than 1200kg's fully loaded, I think the dry weight is around 1280kg's or so, but correct me if I'm wrong.

I agree with the other's, no need for such big brakes. I'd just adapt your stock ones to run a 324mm dic with somehting like the stage 1 kit in the link.

My R32 rallycar weighs 1240kg and has seen a lot of track use in the time I have owned it.

I run semi-slick track tyres and due to the 'challenged' top speed of the N/A I'm usually the last of the late brakers in the turns. So basically I give the brakes Sh#*.

First most important thing is good quality, fresh brake fluid. I run dot 5.1 and I ensure that the fluid is pretty new before track events.

My front brakes are R33 GTS25 2 pot calipers & disks. (NZ$180) Straight bolt on, just remove the stone guards to clear the slightly bigger disks. Pads are Lucas. (NZ $70)

Rears are stock R32 GTS with the same pads.

I have never had any brake fade from these and find them good for all competion use.

Just do what your were planning or 324mm rotors with spaced calipers as mentioned many times before. I have 280rwkw in a street gtr and the spaced calipers stops it fine. In a gts you wouldn't hardly have to use the brakes with a good susp setup.

If your planning to spend $8k on susp and brakes. Just sell the gts and buy a gtr with a few mods for $15k and lap 10 seconds a lap faster than you ever will in the gts with all the mods in the world. Building a track gts is a waste of money IMO and so slow. So many better cars could be bought for the $ you plan on spending.

      I hope it's actually possible. This is a write off in insurance world.

      Yup. 2-way with shallow ramp angles. Still works.

      Duncan's V37.......race car?

      By Duncan · Posted

      That was the first session so not a lot to take from the day. It was low 20s ambient and the coolant had got to 110 (and obviously had some pressure!) so that still needs to be addressed. I haven't downloaded the data yet but will. I had refilled the auto trans with Redline DT6 because it claimed the best viscosity I could find at 100o. It wasn't really long enough to get a good feel for that; while the trans got to 100o in the session it still wasn't shifting crisply as I hoped. I think I'll try a few more sessions before judging. No steering motor overheat but I'd hope not in only 1 session! But finally the suspension; it was night and day over the standard stuff and the car was a couple of seconds quicker on the same crappy tyres, which is a huge difference. I'll stick with that and get some sway bars and a mechanical diff sorted too and see how that all goes together

      R32 Sedan - Grip and Drift (have my cake and eat it too build)

      By CRSKmD · Posted

      I guess it’s partially a compromise of how my car is used, wanting to be able to switch from drift to grip with track side on-car adjustment. Also partially with the way the knuckles are set there is more static camber but less dynamic camber gain.

      Duncan's V37.......race car?

      By Duncan · Posted

      OK, so update from the track day on Friday It was a classic "an unfortunate series of events'. There were a few cars around and when i checked my mirror coming out of the fish hook I notice some smoke from the rear of mine. Looked again and it was getting much worse, I figured I'd blown a turbo or something to got off it and pulled off the racing line. However.... since it is a left hairpin into a right kink, I was on the inside of the next corner. There was a car passing me on the left and a big drop off over the ripple strip on the right......and someone had knocked the witch's hat that was on the apex about 1m onto the track. So, between those 3, I decided to mow down the cone and not damage my car/the other car. Right choice, but surprising result.  The car decided the cone was a small pedestrian so it blew the rear bonnet hinges up to protect their head in the upcoming person to car impact....I didn't see that coming and like an airbag deployment it happened super fast. Straight into the pits from there, everything was driving fine but it became clear it was a coolant leak not smoke, it was billowing up onto the windscreen. Onto the trailer and home. I'll do a separate thread about the repair (once I work out what it is ), but the immediate problem was the bonnet wouldn't open because the front was pinched onto the front bar and would not release. Ultimately we unbolted the hinge from the bonnet, pulled it back a little and it released from the front OK. "There's your problem", the top radiator hose had popped off at the radiator.
