thats what im saying..every car is different, but most of it i have down to a science unless i have a customer that doesnt know what he has. but the 5.0 kits, dont need to have a k member setup, like the mod cars have to, thats why i would still want to offer it as a option. and when using say a upr kit with the on 3 kit, have have to order the hellions k member in order for the control arm cross brace to be lower and clear on3's kit too..lol
but also have to know the limits of what your working with aswell, and high mileage car, can go bad on the dyno rather faster when pushing it past the limits. like the cobra the on3 guys blew up...i knew over 500 at the wheels it was going to go to shit. out at the track, bang goes a rod thru a teksid block..lol but the 2v cars...keep them under 450 at the wheels. and so on..
