what are yours thoughts on running two different types of tread tyres on the rears with a locked diff? i have heard it might be able to break the diff from strain as the two tyres would have different grip temp's... safe or not safe in dry/wet conditions?

The strain on a locked diff doesn't come from different tyre grip levels it is caused by the different speeds the tyres need to travel at and can't because you have a locked diff.

A locked diff on a road car is not legal & is a bad idea.

Under any situation, it makes the car unroadworthy. The tyres on an axle must be identical (maker, model, size).

So you are worried about the tyres making it unroadworthy when he is running a locked diff?

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      Ah yes but were you responsible? In the time I've had it (just before Christmas) I spun off the track twice and drove into things twice, so four separate incidents.. in two outings. Luckily I have a full OEM GTR front end to put on which is hopefully not a precursor for further, future, more expensive mistakes to come. It is some consolation that anyone who would want to buy my Altia bar would have to paint it anyway, the guards, too. (if they can get over the asymmetry). Hopefully over the weekend I will disassemble and see how badly things are bent. From what it looks like, the headlight has actually just been pushed back and bent the headlight support (which .. somehow... crushed the guard in). I guess the headlight plastic is strong stuff.

      These things happen And I believe "we, the people, who modify stuff, and actually use it, cannot have nice things" It's just a shame that it happened so soon after paint  I still win the award for quickly destroying newly painted panels I think, as my car came back from the paint shop all nice and shiny, until about 4 hours later when the boot was destroyed by a wayward locker that was blown around by the wind.... What doesn't kill you makes you stronger, and poorer.....dooh

      R33 disk brake size

      This. And also, the rotor thickness is constrained by the calipers. Cannot be much thicker, if at all. Cannot be much thinner, if at all. New rotors are....fairly cheap. Turbo calipers can still be picked up for sensible money. Arguably, the best thing is to get R32 calipers and put them on mount spacers on 324mm discs. That's about the cheapest and easiest way to get quite large brakes that are essentially bolt on. And that's despite maintaining for years that the R32 calipers are not the best choice because they seem to be more flexy and creaky than the others. If you were prepared to put up with nasty little NA sliding calipers, these will still seem like Brembos by comparison.

      Why would you not fit the biggest possible brakes?
