I'm slowly gathering bits and making plans for a Micra engine conversion; I have the engine, subframe, driveshafts, some throttle bodies, a fancy computer and a few other bits.
The current setup is 7.5" Cooper S discs, with a servo. The car is a Minus, so the servo already sits above the bonnet line, so regardless of how I end up doing the Micra conversion, I want that gone so I can fit a bonnet without a massive daft bulge. No experience of the brakes without a servo, so interested in whether it's worth swapping to 4-pot calipers when the servo goes? I understand the argument that you can still lock up all the wheels, but that's the same argument people used against disc brakes on mountain bikes. It's really about pedal feel and how much work you have to put in to stop, rather than ultimate power. I don't want to lose the 10" rims, so interested in the best performing 10" setup that doesn't need the pedal mashing too hard.
Secondly, if I go the ITB route, the master cylinders are then in the way; I know Willwood will sell me a pedal box for lots and lots of cash, but are there any options that are more sensibly priced that are worth looking at? Is suitability for the mini determined by the diameter of the master cylinder, or is it a combination of the diameter and the leverage ratio that the pedal applies to the cylinder? ie the volume of fluid for a given amount of pedal travel?
Not in a rush ont his, but would be handy to have a better idea of what I would be after in case something comes up second hand etc.
Thanks!
