I use studded tires, 120lbs of sand in my trunk and my T-Lok.
It does amazingly well with just those three things. It'll push its way through fresh snow and does amazing on ice and compact snow.
2000 Prochaged V6. T-lok, Mach 1 takeoff exhaust with H-pipe, 20% tint, OEM fogs and all HIDs.
SAE Corrected: 289HP/298TQ at 5100RPM(Pegged MAF).
