I know a few people who've told me when they call or visit rally design for parts for their rod/custom the people they spoke to weren't very helpful. Mainly because they don't understand 'our' type of cars so they want you to tell them exactly what you want. You may need to talk about options so now you can. I've worked here now for a bit over a year so if you need a technical chat or advise/recommendations ask for me, Neil. If it's brakes tech stuff Andy is your man, he's been doing it for years.
Cheers, Neil.
