Lightbulb Suspension Questions

I have recently picked up a set of lighter wheels (carbon fiber) and rotors. I will be purchasing some Ohlins R&T forks and rear shock. Do the lighter wheels effect the spring rate that I should choose? I have heard mixed replies from some of the phone calls that I have made.
To me, it seems like it wouldn't effect it because you have the same weight sitting on the suspension, but others say the rebound is effected

I also picked up a full set of carbon fiber fairings (Upper, belly, tail, tank panels, airbox, fenders). This should effect the spring rate, but is it enough for me to pick a different spring rate other than the one for my weight?

carbon fiber isnt that much if it all lighter than plastic, IMO

wheels are unsprung weight, it WILL affect your suspension characteristics

I was told... "Yes it does effect it".

Further more depending on what size (width wise) tires you intend on using you may even need this: http://www.gravesport.com/cgi-bin/sh...&key=SP__4004A

If the bodywork/wheels put together and more then 20 lbs of a difference on the suspension, I would have it reset to your liking/weight by the "same person".

Black Widow:
Thanks. I planned on ordering that mount since I run the 55's. Is it a 1:1 comparison on the weight; i.e. order a 20lb. lighter spring?

YellowJacket:
Won't make TWS (Texas World Speedway). Wish I could. I am working, but plan on taking vacation soon and will be signing up for one on one training with Larry Meyers at MSRH. He said for $500/day, you ride all day, track basically to yourself and him. If I get a few others to join in, $300/day.



What's with the poisonous insect/arachnid names, guys?

its going to affect it, losing unsprung weight is a great thing to do, but you will have to adjust your suspension. Whether or not to go stiffer or softer though I'm not sure. depends really on the actual weight loss.

start by springing to your weight in full riding gear,
the lighter wheels will make the bike more responsive on the steering side but modern day sports bike wheels aren't that much heavier, not like the old days!!
If by being more responsive you can better your PB's then changes may be in order!
I doubt the carbon bodywork will make any difference at all to the average track rider & novice racer settings!!
the advantage at the real sharp end of things on bikes that are weight restricted is that it allows the weight to be placed where it is most advantagous (normally not up top)
