im starting to look at suspension now as ive finished the engine turbo remap etc so was wondering which size springs i should use or how many mm to drop it by changing the springs also any other mods for a bug eye that would better the suspension maybe droplinks but i dont know much about them or what they do

 

For looks (and handling) lowered springs will improve the handling.
An adjustable rear Anti-Roll Bar (ARB) will reduce understeer and the car will offer oversteer on demand... LOL. Uprated drop-links "help" the ARB work.
If you are at "The Ketch" next month you could try my bug-eye, std suspension with ALK and up-rated ARB's & drop-links front and rear...
