on my car, brake & clutch can be adjusted high & low. For me, the brake pedal cannot be higher than the gas. This depends on the full lock position of the brake on each car. When u enter a corner & H&T, u wont brake until
the pedal is at it's deepest position. When the brake pedal is adjusted higher, the full lock position will rise too. Normally the comfortable H&T position when we feather the brake is toe low, heel high. Only then we can blip the gas properly. I dont know if my explanation is clear to you, but it all depends on your braking amount & blipping technique.
To me, dont listen to whatever others are gonna say to u. Just mod your pedals base on your own feel, comfortability & technique. On the spacing of your pedals, u can get chose screw-on pedals & shift the position of left/right during mounting. A more drastic method would be rewelding the mounting base plate according to the spacing that u wanted. Either that or u can dismantle the whole pedal & do some bending & rewelding of the pedal leg if u really want the right distance.
I changed my brake & clutch assembly to a different car model before because the spacing is better. I drive a toyota & a lot of parts from other models within toyota are plug & play sometime, so it's easier. I'm very picky on my navigational & seating ergonomics in my car as I'm very tall & cant really fit into japanese car without modding them for my driving pleasure.
