i'm the same i have a uk300 with paradas and i run 35ish front and 33/34ish rear, any lower and the car feels wobbly like the back is always catching up, i've got white line ARBs back and front, ALK and EXE TC adjustable coil overs. I did have P-zero Rossos before and if they were anything near 35 i would be all over the place in the corners (very Top Gear, smoke the works, looked cool but was terrifying).Anyway thats my 2ps worth. But as renny says it is down to what you feel is good.
