That's my point. There are too many variables using the solid shock method still. Yes you are eliminating the shocks and springs but there is still slop, chassis flex, arm flex, tire flex, etc. affecting the outcome. If all these come into play in one form or another you will be adding weight to the car to corner weight it incorrectly. It just seems ridiculous to worry about 1/2 ounce on an 8 pound car.
I corner weighted my losi 22 with the shocks on and the rear was eqaul within a few grams. The front was off 50 grams side to side. It turns equally well both ways and the rear end doesn't step out under acceleration. Good enough for me and 99% of the rest of us without getting totally anal about stuff. If I can't feel a difference with a 3 pound buggy then I'm not even going to waste my time with my 1/8 scale.
If you really want to check corner weight put the chassis on scales with equal length standoffs. Take as many variables out as you can. I just hope the chassis is perfectly flat or you will be chasing your tail again.

Larlev, someone was supposed to send me Losi shocks but i havent recieved them yet and i cant remember who it was.

Thanx marcus for doing the test. While i personally dont have the solid shocks i still enjoyed learning something! There is math and then there is actually doing something. Some are content on armchair quartebacking but you took the time to try someone elses idea and then share the results with us. So thanks man !

Before everyone unsubscribes, I'll throw in that I've read and reread this and did the spring test on my TLR 22. With a video camera slowed to 1/16 speed my result was that any combination of red or orange fronts combined with white, yellow, or pink springs showed just about the same result: no major porpoising. The testing was done by pushing the car down at the front/rear balance point and watching which end went up faster. I tried the test by dropping it from a few inches high, but that seemed to be a less reliable way to get a consistent result. There was some VERY minor front or rear bias with certain spring combos, but it took a slo-mo replay to catch it. Not sure if that would translate into feeling a performance difference on the track if it's so minor. Red front with Yellow rear seemed to be the same frequency (kit settings, imagine that!) as was Orange front and Pink rear. If anyone came up with other results, I'd be happy to hear it.

Correct, without oil. Just springs and brand new rebuilds of all the shocks before the testing.

I still think this still a positive thread. I've been following it just to get new ideas and possibly 'unlearn' what I thought was true. I've learned a few things And sometimes I just have to agree to disagree and move on... This IS a forum for discussion, and from what I see you guys are just disagreeing on one point. That point is "How much detail makes a difference you can feel/measure on the track"
But I do agree all the things discussed do make a difference, some of the things are not worth my effort however. For some they might be worthwhile.
If you want to end the debate on this corner balance accuracy and how far you want to go. Define how accurate we need to be using raw numbers. See if it's even possible within the time take and money you want to spend. Once that's defined either do it or move on...
Keep in mind my interest is offroad, some of the theories discussed here, at least to me, are impractical due to the balance of time/cost/fun.

Trevor, I could argue there are exceptions. :P

lets just say our peice and move on. this forum has taught me alot and i refer to the original ideas quite often. If you dont like or agree with a way of doing things say it say y argue it once and move on. its really pretty simple.
