I think Clayton and I meant unsprung weight as in steering knuckles, not rolling mass like wheels and tires. A reduction in rolling mass (also part of unsprung weight) will improve acceleration, but lightening your steering knuckles or control arms won't do squat for your acceleration (unless through the overall weight reduction of the car) Denis > -Brett. > '90 GLi (Currently on 14" Teardrops/ Dunlop Graspic Snows, 15" Corrado > Wheels/ Dunlop SP8000s in the summer) > > Clayton <[email protected]> on 01/27/2000 11:48:00 AM > > To: [email protected], [email protected] > cc: (bcc: Brett Haney) > Subject: Re: The beast revealed! > > Unsprung weight does not affect acceleration at all.
