[QUOTE="Jdm351, post: 14635139, member: 167713"] Just got a pair of 15 x 8 RTS wheels and 26x10.5x15 Et Street Bias Plys. I weighed this rear tire package and each was 35 lbs. The stockers are 55 each so a huge 40 lb rotational weight loss. Went to Wildhorse Pass Motorsports park last night to try them out. Dead hooked every pass at a track known for little to no track prep and traction. I was happy about that. However, the best 60 i mustered was 1.89 with 4500 rpm clutch dump. Do I really need to raise that rpm to drop the sixty down to 1.6 or 1.7x? I've seen relatively stock cars like mine (axle back, drop in filter) in the 1.7x range on the intraweb and kind of expected to do that pretty easily. Also, my 1/8th mph was sub 88 mph and I have seen others at 90mph. I picked up 23.5 on the big end and thought that is pretty good, just need to find more on the front half. Will a 6k rpm clutch dump drop the 60 another .15 and bring me into the low twelves? DA last night was 12-1500 ft and this is an manual 3.31 gear car.
