[s-cars] About RS2 ebrake

[Jani Peltopuro]

Hi,

a comment about the RS2 ebrake: a sh*t system. :-)

Most common failure of the RS2 is that it is not
functional. Even after rebuild I struggle to lock rear
wheels in snow, and after a while, the ebrake has no
effect whatsoever. So at least it needs frequent
maintenance (not just use!) to work.

I know Dave E. has a functional ebrake in RS2, but I
don't think his car meets snow, salt and slush.

So to anyone living in "quattro"-climate, and thinking
of a rear brake upgrade, I'd consider a separate
caliper for ebrake.

In general to rear upgrade, at least RS2 with 993tt
caliper (44/36mm pistons), 322x32 discs and rear
299x24 discs with 968CS (30/28mm) brakes works great.
No fading at all on track, though the car weighs 1650
kg.

I know some people say you shouldn't upgrade rears,
causes instability. RS2 weight distribution is
56%f/44r. The brake balance is a little oversteery if
applied abruptly in corners, not disturbingly, just so
you can use it to your advantage. I think in a
straight line the rears do help braking more than
you'd initially think.

Regards,
Jani
