Thanks for that Komdotkom Does anyone by chance know what the thread is on the end of the hard line of the GTST front brake system before it goes to the braided line - will need to get a fitting to put in there as you say. Could you do this with the caliper on the car? Just get the pistons all the way back with a spacer or even some clamps? Im running a 36mm disc and 18mm pads - the pistons are almost as far back as they can get but i think with some old pads and a wedge I can make sure. Just easier if the caliper is mounted to something.

Agreed. I will do this....although not sure how to bench bleed a caliper. Will have to find some gear or use the little vac pump I have. There are AKB springs in these. Although I feel like they are only on the large piston....although I could be wrong there. So can't push them all the way back.

I do - but have better results with the pressure bleeder. I could try the vac bleeder and see if it gets any other bubbles out. Will see if i can find it.....got relegated a while ago!!

Yep - i went from furthest away to closest to MC - both sides of each caliper - then came back and did it again to make sure.

Good plan. I will do that for sure. havent actually checked to see that all things are happening as they should on each side of the caliper! And yes, i agree, it seems super odd that a caliper can be so bendy. Im just struggling to find an alterante explanation.

This would be the only reason the dogbone would flex - pushing/pulling it based on unequal load. Not sure how to check for this besides putting a gauge on each bleed nipple and giving it the berries to see what pressure it reads.

I did think of this - i unbolted the caliper from the dogbone so it was just resting on the disc and the result was the same - the caliper spread about the disc. Ill do this again and get some video this time. I did also use a digital caliper when fitting the kit - the misalignment of the disc to the caliper was <0.5mm. The shims I have are 0.5mm so i wasnt really able to improve alignment. Seemed pretty good off the bat really. I tell ya - this has me thoroughly confused

To be fair im not sure - i have bled the system a lot of times - the pressure bleeder i use has worked a treat on previous setups on this car. So i would assume its doing the job here also...... I did also bleed with the pedal later on just to be "sure" - didnt make a difference.

Hey GTSBoy - I used a pressure bleeder to bleed the kit - didnt do pedal bleeding at first. Issue was still there. When you push the pedal you get the caliper flex - so the fluid is going to the caliper - its not bypassing within the master itself

Hello SAU, I recently purchased an Alcon TA6 kit through a QLD company who supplies the dog bones/rotors etc. The kit has 356x36mm rotors - aluminium dog bones - TA6 calipers. I used the HEL brake lines I already have. Kit appears to be of high quality.....as much as visually i guess it can be. What I have noticed after install and pressure bleeding (and pedal bleeding) multiple times is that the calliper is flexing a decent amount when the pedal is pushed - enough that i can push the pedal to the floor as the calliper just keeps on flexing. Details: 1. OEM master cylinder @ 15/16" (BM44 - non ABS GTST) 2. OEM everything else on brake system - rear callipers etc. Just braided lines (front/rear) and the TA6 front kit 3. The TA6 calliper has ~2% smaller piston area than the OEM 4 pot sumitomo calliper - so no issue there.....i dont think. TA6 is 27/31.8/38.1 and OEM is 40.4/40.4 4. Have checked the calliper flex with car on (booster assistance) and off - same result just have to push harder with car off 5. Have unbolted calliper from the dog bone so its just resting on the disc and tested again - same thing - so flex of the dog bone doesnt seem to be an issue 6. Tried to measure pedal ratio as best i could - looks to be about 4.8:1 with some margin for error - ignoring the booster with 50kg of leg (beeeefy - but with booster probably fairly achievable) thats about 770psi of brake pressure which doesnt seem super high - but maybe it is?? So 75kg of leg = 1150psi. I guess my question is - is this normal? Alcon distributors over here have been helpful but ultimately have said its normal. I feel like modulation is bad as only the first 30-40% of pedal pressure/travel does anything. After that its a mix of flex....and maybe some extra clamp force. My old setup - Ksport 8 pots with 12 years of track work on them did not have this issue - pedal was solid. Only reason for change was a hub failure caused the disc to tear one of the callipers to bits. Thanks SAU - any thoughts/help would be appreciated. 20240303_124128 (1) (1).mp4

265/35/18 AD08R - Used Hello, Have a used set of AD08R tyres for sale - 265/35/18 x 4. Have done 10-12 track days @ QR, Lakeside. Still have quite a bit of tread. Did a 58.05 at QR sprint circuit with these - plenty of grip for a street tyre! Have moved onto semi's. Available for PICK UP ONLY in Yeronga, Brisbane. Want them out of my garage - $220 Cheers, David

Sold pending payment. Thanks

Bump. Good road and track setup.

No they are like new. I used them on my track car. Does track days and a few battery charging k's every fortnight. Total of maybe 3000 kms at the most. After re-valve probably only 500 ks. Cheers

Price drop to $1200. Cheers.

Hello, Im selling my shockworks adjustable coilovers for R33 GTST. I purchased these new in 2014 and also sent them back earlier this year to be re-valved with the latest settings from Shockworks. Have moved on to a more track focused setup. Price: $1300 pickup - Have a coilover box so can post at buyers expense Location: Brisbane South Side (5kms from city) Condition: Excellent 8 kg/mm Front and 6 kg/mm Rear 12 click damper adjustment Adjustable spring seat and body Set to heights that i used for the track Times on these coilovers: 58.12 at QR sprint on AD08's 59.8 at Lakeside on AD08's These are a great compromise for street and track. Comfortable on the road but still up to the task on the track. Contact: PM me Regards, David Madden
