Buy PS-II over stock RFT's
Pro's
1-Loose 12 Lbs of unsprung weight
2-Better gas mileage ( +2 mpg for me)
3-faster acceleration ( less unsprung weight)
4-higher cornering limits (.95 g's stock .98 with PS-II's)
5-better wet and dry traction
6-longer tire life
7-less replacement costs
8-better ride quality
Con's
1-no spare
So thats 8 to 1 any questions
