this months redline is all about weight saving and unsprung weight and that and as got loads of tips into might be woth a read for you,
eg like saving 5kg a on a wheel equals to a total of 80kg through four heels as unsprun wieght as four times the effect or sumat like that
yup read it a few times, great mag now is redline. Especially the other month as it gave me 20 free laps of the ring, so more than happy
