@jasonfreed .. G’day Jason, sorry to hear engine is coming out, but it could be much worse!… please remember to share whatever they find inside with us. I’ll be keen to learn what can cause this.

that's what they are trying next - thanks!

Yes, they (Team Stradale) replaced it thinking that exact same thing - did not fix the problem (and I actually inspected the old bearing and it seemed to be in good condition).

No, I have the fixed smaller brakes. To be clear, I have not actyually bled my brakes during sessions, only in between events. My local track, I cannot express how hard on the braking system this t...

It must be good stuff. When you do bleed, do you notice any tiny bubbles? For Radical, I have always used the Motul RBF 660. I always see two to four tiny bubbles when I bleed the brakes which is b...

That is what I meant. I mispoke. If the pedal went all the way to the floor you would have little or no braking. I was at the track last weekend with my spec racer ford. I had a similar experienc...

I think it would definitely be worth doing a full replacement then. I'm normally able to do it with a standard 500ml container of fluid (I use Motul RBF660) as long as you don't "overbleed" any one c...

@meatman - G'day Josh. Like Charley - I've never heard of anyone having issues like that, and certainly not to the extent that requires any bleeding to be done in the middle of a race event. These t...

@meatman That's certainly not my experience. I use Castrol SRF and typically only bleed brakes when I change pads (2-3 times a year) and/or rotors.

The spec from the owner's manual is Motul RBF 660. I would use that, starting with a full flush. The lifing schedule on master cylinder is 8000 km. If your foot is sinking to the floor, I would re...

Attachment : IMG-20230321-WA0004.jpg Hi! Im from Poland and I am an owner of Radical Prosport chassis 0082. I have tried it only once on a small track but I am already a big fan of it. I hope it ...

well, first time back on track in 2023 - a perfect day. Setup honed a little more, a shorter ratio (1 lower than factory standard), newer pads, and a lot more confidence to attack. Ended up doing 82 l...

@alex-heavens -G'day Alex, You noticed the threaded holes - Well spotted!... yes, will help get it apart without causing damage to the mating faces. I agree with your comment about first gear at idle...

Hi All, Just a bit more of an update on this topic.. I feel like I'm starting to understand what's required here. I now own three of these GDU's (one in the older RSX I have, a brand new one in the XX...

@rjbender That’s really interesting 👍 It sounds like Radical have ditched the oil cooler and replaced it with a heat exchanger for the XXR? Not sure about the 1st gear at idle part of the manu...
