I race on a State and Interstate Rallye at Fortaleza - Brazil. Just bought a one cabin Toyota SR5 - Hilux, it is probably the 4runner. Being used to a 2 cabin, I would like to know what should I do to keep the rear from oversteering, once the trunck is light and the leafsprings kicks the car up on a irregular ground or sand dunnes as we have here by the coast.
Any clue on springleafs and proper shocks?
First your leaf springs are probably for a heavy load and have too much ' spring ' to them.. TRy a set from Deaver 714-542-3703 or National Spring in So Cal. .. They will make a custom pac designed for your vehicle and driving conditions.. After that find your shock from Fox, Bilstein, Sway-A-Way or King.. They make the sock for what you are trying to do.. http://www.kingshocks.com/ http://www.bilstein.com/
I wouldn't worry much about the fact that you've got an extra "Cabin" attached to the truck. The main thing is getting the right spring/shock combo on it. Weigh your truck at each corner and call National Spring in El Cajon, California for the supreme set of springs. For shocks, I'm a huge Bilstein fan but you may have better luck with a company like Fox Racing Shocks. Either way, that's your call. Good luck! Report back.
