Nothing you do is manageable on the wallet.
Tbh if you can lock the wheels then surely no point in going bigger?
What pad you aiming to use. I guess keeping these working at their optimum is more important.
the key to big brakes is being able to NOT lock the wheels.
even stock brakes can lock the wheels at 100mph with a hard stab of the pedal, the secret is in the modulation and feedback and feel you get from a big brake kit.
With stock brakes, you get a set amount of retardation, that the tyres cope with easily, then you press a bit harder, and due to all sorts of issues with caliper flex and other things, you don't slow down any more, then the wheel locks up, and then you're not slowing down at all.
With big brakes, you're able to modulate that power right on the edge of the tyres limits much better, braking right up to the point where you can actually hear the tyres about to let go, and holding it at that point of maximum deceleration without ever actually locking up.
We'll go to 335 next time, simply because the 335 discs are only £5 more than the 330's, and we will go for a wider disc to increase the air gap between sides of the disc, so increasing the amount of air passing through the disc and thus the cooling capability too.
Pad wise I'll be sticking with these RS29's for as long as possible on these discs, then have a re-think when it's new disc time.
Power wise, we've never wanted anything more since the LCR brembos, so it's all about heat management now.
Main reason for floating is to eliminate the risk of judder when hot, as we seem particularly susceptible to this for some unlucky reason.
