Hi guys,
Thanks for the replies, sorry it has taken me so long to get back to have a look at the replies (I'm currently working in the middle of nowhere about 4500 km from home).
To answer the question of what I intend to use the car for, Hill Climbing and Circuit Sprinting and maybe some Cafe cruising.
I was looking at having it installed by someone for no other reason than its quicker and I don't consider a half a days labour that expensive. I work remote so I figure I can always make more money, I can't make more time.
Cheers
Adam
