How much of a difference does lighter wheels make in the 1/4. I'm planning on using my tax return to get some 16" Motegi MR7's with BFG g-Sport 205/45ZR16. My best run so far is 16.062@86mph with no back seat/subwoofer and amp and half tank of gas. I'm aiming to break 15's.

 

I think the rule of thumb is for every 100lbs of weight reduced is worth a tenth (.10) of a second in the quarter mile. Not sure about unsprung weight vs. sprung weight though.

 

Who cares if it's fast if it's not sexy?

Anna Kournikova - Sucks at tennis+hot = Super famous
Maria Sharapova - Good at Tennis+hot = Super famous
Amelie Mauresmo - Current Tennis Champion+ not hot= Who?

Keep it sexy bitches!

 

good stat... you are absolutely correct... From my years of drag racing experience... 100lbs of weight does equal .10 and 1mph in the 1/4. HOWEVER when you are talking about rotating mass... that number increases. So it is definitely a valueable investment. As you will likely see more than .10 and 1mph with a reduction of 100lbs of rotating mass. Also, you will find a very nice gain in ET with the addition of drag radials... drag radials alone are likely to get you into the 15's. We run and sell the Hoosier DOT drag radials and would recommend them to anyone. They have many sizes from 15 up through 17 inch.

 

Best Quote ever.

 

Rotating mass does make a world of a difference. Makes me wish I had just saved up the money to get the lightweight 3-piece wheels instead of my Hot Wheels. But I still get mad compliments and looks and stares everywhere I go. That leaves me content. Plus I can accept the pothole I hit a few months ago better with such a frugal disission.

 

How much does the pass. seat weigh? I was going to take that out at the track but didn't have the right size socket. I also had no spare in as well.

 

the lighter wheels would def be worth it...and if your gonna get some BFG's, you should consider the GForce KD or the GForce KDW....both bada$$ tires

 

Can the stock axles hold a drag radial launch? Ouch that just sounds rough.

 

stock axels + drag radials + good clutch + good Tq + good driving = snap

 

oh, and the passenger seat is pretty hefty. not sure on exact weight.

 

I know a guy who snapped his axle. He wasn't too happy bout it.
