Hey guys and girls
since we all have different opinions on this topic, i have created a thread to discuss our theories...

i have done a small amount of research and have found that u must first set the static weight as close as possible 50/50 in the front, then adjust the coilovers for crossweghting...
sorry if i have offended anyone i am pretty passionate about my datsuns and can get a bit carried away sometimes..
regards
Daniel

this site is good .... click here

this is for circuit use?

i think it refers to autocross / road use.

who corner weights a road car? complete waste of time when you have constantly changing payloads - passengers and stuff in the boot or tray etc

its generally only used by top end race cars chasing a handling problem after exhausting the normal tuning techniques. I'll eat my hat if anyone on this site (with the exception maybe of Cameron) with a race car has actually set cross weight on their cars as part of their setup!

Road=tarmac what is ur point here? some of us like to go out to track day's and will benifit from this thread..
u can set ur car up for the driver only??

i posted this thread up so we can get some positive info...
maybe u would benefit from corner weighting in ur new coupe....

See what I meant by saying the driver's side spring is a little firmer than the other side to compensate for driver weight that is ALWAYS persent in a car.(Normal road use).
I agree that this is for road cars, and not applied to race cars.But must it not still be taken into consideration when setting up corner weight for racing?

I agree. We are not driving Formula 1, Indy or NASCARS here.

I'm giving you positive info, its just not the info you want to hear. cross weighting is best left until after you have exhausted the normal tuning techniques. springs, shocks, bars, geometry, ride height, etc etc

even then its going to be a fairly minor change anyway. Take it from someone who has run alot of speed events with quite alot of success and also done road rallies every year in the same car with a navigator in the passenger side - that's alot of weight (~80kg) moved around in the vehicle which weighed 851kg, so its damn near 10% of the car's total weight and would have to have a significant impact on the corner weights, but I'm stuffed if I can tell if it changed the handling at all!

also, I used to dual enter the car with a mate with about 40yrs of competition experience and we did alot of tweaking at the track with it. He weighs 30kg less than me, which is also a huge amount of weight in terms of this kind of adjustment you're talking about and we both found the car handled the same for each of us. And when we made a change, we both came back with the same conclusions - eg, ok that's fairly nuetral now.

You either need to have a very sophisticated and sensitive race car for this adjustment to make a useful contribution to performance - eg lap times, or be racing in a single make category chasing every last hundreth.

either that or you can feel a pea under 9 mattresses, or however the story goes.

lol
i havn't done it to any of my road cars.... yet
but i do plan to race in the near future...
and it's not as hard as u think..

"One of the most important aspects of racing is having a good handling balance. Setting static weight distribution and adjusting cross-weight percentage is one way to assure good handling. Taking the time and making the effort always pay dividends."

i just quoted that from the end of that article.. so true

I used to do it on my race coupe, we did it on our stock cars {dirt} and I do it on my sons karts, every little bit helps, but they are expensive to buy. Setting cross weights on a leaf sprung car would be interesting.. another advantage in using coil overs.

I can understand it in all those situations:
- your race coupe was a very highly developed machine from what I've seen.
- karts - every hundreth counts
- stock cars - wedge is a very useful tuning device for oval racing.

for road cars that do an ocassional track day? much better off sorting out alot of other things that will have bigger impact on your handling than cross weighting.
