Wheels, tyres and pads or save for diff?

[torqueofthedevil]

Really wanted an LSD diff on my sprint car for a while now (fwd) but can't justify the expense - diff alone £700 then fitting etc. Currently running standard alloys and different tyres front and back and standard brake pads. Do u think that getting quality tyres (not quite semi slicks but almost), lightweight OZ alloys and some decent brake pads would actually make me faster? Suspension is quite good, but under harsh cornering I do tend to lift a wheel and spin the wheel due to the open diff.

Tyres, brakes, diff in that order, if you have the cash later change the wheels when the tyres wear out

If it's for competitive sprinting, make sure you've read your club's technical rules as you may find mods affect your class and the extra speed you've now got is negated by being in a class with faster rivals.

Check the regulations, they are usually have restrictions on tyres.

I'm not sure if brakes will make a massive difference. I remember someone saying that, as a rule of thumb, if you can lock all four wheels then your brakes are powerful enough. Is overheating an issue?

I'm clued up on regs so I know lll be ok there. I can't really lock wheels up, can't afford bigger calipers so hopefully some mintex 1144's will do the trick.

Depends, decent pads tend to be more consistant and the extra torque reduces flex in the system which helps with pedal feel and control, which can help you hold the car closer to the point of lock up.
