Front calipers on the back

[foz01]

Anyone done it, i know about the loss of handbrake etc but is it bolt on or is there more to it?


cheers

It's not bolt on, the caliper mountings are completely different.
You'll also need to do something about the brake balance as the piston surface areas are totally different.
All soluble problems with some research and an engineering workshop.

If you're looking to get more braking at the rear, you can machine out the std caliper to take a 40mm piston and get a good bit more rear pressure. Some info on seloc here. Its a mod I intend to do when i've got the cash for an AP upgrade at the front.

But in anwer to your question, nope I dont know anything about putting front calipers on the rear

What he said.

p.s. I wouldn't bother if I were you. Not really worth the effort.

Are these S2's really so heavy that the standard brakes are not good enough ?

Can you lock your brakes in the dry with your current set up? Bet you can. If so you have enough brake power! You can't get any more braking power onto the road. Stickyer rubber and better suspension setup will enable you to, if its fading brakes, then that is a different problem that will not really be solved with bigger calipers.

Looking to put 4 pots on the front so just thought abotu beefing up the rears as well, if it involves lots of buggering about then i wont bother, as for locking up, the fronts yeah easy, the rears, dont think so

As I say, its worth considering for the little cash outlay....

Something seriously wrong with your brakes then . . .

Aye, bias...

Was dont think so as in i am not aware of locking up the rears, not as in, "i dont think so lol "

If that makes sense!?

Ok, will look into it- rears are looking pretty sorry for themselves i have to say- could do with a rebuild and if was doing that would get the cylinder bored out

[steve_weegie]

Aye, the graph down the page speaks volumes when tested on the viper. My plan was to machine out to 40mm and see how the balance was after that. If necessary, an AP bias valve could be added to move it about a bit if needed.

Alternativly you could just move the bias forward with a bit of left foot braking

[fd]

So . . . y'all think the bias is wrong on a standard Elise then ?

On track if I put my foot on the clutch when breaking on the ragged edge the rears will lock . . . I stop this by leaving it in gear . . . as you're supposed to . . . any more rear bias and it'd be very difficult to brake hard enough as the rears would lock far too easily . . .

You are driving Elises right ?

Sure if you change the fronts then you'll screw up the bias . . . but stock the bias is pretty much spot on . . . IMHO . . . and in thousands of laps of KH I've never needed any better brakes . . . apart from in the caterham where I can destroy the brakes in about 30 minutes . . .

Ah no sir eee, I only think the bias would need adjusted if i was fitting big AP rotors at the front

I need the bigger AP rotors, as i buckeled the eliseparts bells after an enthusiastic session... But not everybody brakes as late as me

Some air scoops for the drums might help? Slowing down is also another option
