Default Wheel and tire swap

Here's what I am running at the track

17x9 ZR1 with 245/45R17 in the front
stock painted 16x8 firebird 5 spoke with 28 11.50 bias ply et streets

Here's what I want to run

summit star 15x4 with radial front
summit atar 15x8 with 275/50R15 drag radial (~26inches tall)

Would it be worth the time and money? I don't have the cash to blow on real welds but I want to get back to a 26in tire and some lighter wheels.

Judging by your sig those 28's are probaly killing you. The switch to 26" tires alone should net gains. I have that exact wheel/tire setup your looking to do and it works real well for me. The rear will probaly be about the same weight maybe a tad less but the front will be a decent amount lighter than your ZR1's.

I need to update the sig but add a 224R, ported 241s, 85mm maf, and a 3600 stall. I figure the tire height is what's really killing me. Plus I'm sick of taking the laptop just to change for 28s.

SUM-521-5862PS I did a quick test fit last night and it doesn't appear that I have to do any grinding at this time. That may be a different story though once the brakes heat up. When I get the fronts I'll let you know.

I got the wheels on the car with the nexens up front and hoosier 275/50-15 out back and I have no clearenec issues. No grinding needed even after putting some miles on them. We'll see what it's worth at the track this weekend if the rain holds off.
