Which spring weights did you go for?

I had mine corner weighted and aligned at an MX5 specialist with racing experience.
He wanted to get 1,5-2 degrees camber on the front but could only get 1 degree in both sides for some reason (something about how much adjustment there was available). It feels great with a bit of camber on.

@Lee had my car set up pretty well from his garage floor so was only a little bit of adjustment was needed to get it to what I wanted (my brief was low as practically possible without grounding/rubbing and set for enjoyable road driving):

The specs on mine are now:
Weight of driver: 75kg (the actual drivers a bit heavier now..!)
1/4 tank fuel.
LF 335kg RF371kg
LR 338kg RR364kg
Cross weight 50,3%
Total weight 1406kg

Ride height
LF 5"9/16 RF 5"8/16 (from front ARB)
LR 7"7/16 RR 7"3/8 (from rear beam)

Camber -1 degree both sides (front)
Front toe: 0,5mm toe in

Lots of BC racing talk on this thread:
