Default Brake pedal boxes etc?

Ok, I have plans for my RS1600i over next winter which include more power in turbo form. Im collecting things now ready for when I do it. One thing though as you all know is RSi's suffer from shocking brakes so I dont want to up the power and not do the brakes too!
What options do I have? First thing I though was pedal box, but to tell the truth I know nothing about the subject!

Cheers

what size wheels will you be using? std?

if so, i would run cossie set mine was good

its the bar that runs across the engine bay thats the poor bit
could run a brace to servo as this will flex

if you go for a pedal box go for a floor mount
i have a willwood jobbie and im soon gonna be changing to a floor mount from obp

Cheers Gus yeah going to run srd wheels I want it looking atd as possible....IE running megajolt and keeping the twin coils! Regarding the transfer bar yes thats my point mate I was thinking of options to do away with that! The rs1600i's came with servo brace bars anyway and theyre still pants! Its strange as the brakes on my mk3 Ghia are spot on and brake to the touch!

As above, brakes arent too bad on a 16i its the bar and the linkage that boreham designed to make it fit RHD thats the problem

If you can see where it flexes the bulkhead where the linkage is then you could weld in some support which will cure the spongy feel ( bulkhead flexing ) then you could just upgrade brakes in the normal way. I know a few peeps who have done this over the years

They should have used the same setup as a 3i but the bar didnt clear the 16i inlet manifold i think

yeah thats why the XR3i inlet is angled mate to clear the brake fluid res/master cylinder.!

Obviously Id like to keep the std setup in the bay IF I can get good brakes. Whats the max size 4 pots and rotors you can get under 15's? 300mm?

Gus, have you got any pics of your Wilwood pedal set up ? I have a bias box in mine but would like the master cylinders inside the cabin under dash.

thats about the only one i have that you can see it fitted

i wouldnt recommend this one tho, we just cant get a good pedal with it and i dont have much confidence in the middle pedal

i would go for a floor mount (which is what we are doing)

Same problem with mine, can't get a good pedal and the injection system only just misses the cylinders.

I really didn't get on with my pedal box. Hated it infact. Seriously lost confidence in the braking power even wioth AP 4 pots and 330 mm discs.

Best setup I had on mine was the 300 mm discs with Mondeo calipers. They were the tits. But they won't fit under your standard wheels

Thats trouble, and I really do want to keep 15 inch 7 spokes although I could be swayed to fit 16inch comps if I really had to but not first choice!

dont think there is anything wrong with the willwood pedal box, its just not the right application for my car

i brought it after a mate brought one for his

turned out his brakes wasnt upto much either

should of just listened to the people i had putting the car together (did in the end)

i just not go enough travel on my pedal

do you mean your pedal is hitting the bulkhead or your maxing out cylinder travel?

as mine seemed to be pretty good imo and would lock up if you tried.

few pics of how mine was mounted

yeah it was a bit of a pain fitting them, mine does also hit, but the brakes were locked up well before then.

the pedals are a bit long on them imo
