Just wondering! i heard that the best superlows for v8s are to have normal low I6 springs in the front?

Do you mean that you heard superlows for V8's are the same as Low's for I6's

out of the box - they probably look similar - but on the car, they will look lower.

Remember - the V8 engine weighs more than the I6, so they are designed to hold up a lot more weight.

Yeah kelly just int he kings catalogue at work they dont list superlows for XE V8 but it recommends to use I6 Lows front and I6 Super low rears
