Help on weight distribution and/or weighing of

[yellowshark]

For the 1st time ever I have had a go at taking the weights at the individual wheels. A bit Heath Robinson as I only have two digital scales of usable size. I made sure they were level with each other and I put a couple of books behind them (centred)which after plenty of trial and error were level with the scales (almost).

I placed the rear wheels on the books and then lowered the front onto the scales and noted the readings. Then I reversed the process and measured the rear wheels, remembering that what was right was now left. ;D

We are not talking clinical accuracy here, there was an 8gm difference between the scales in just weighing the total car, but....

Front vs rear was 660 vs 700 Easily fixed as I added some weight for the BTCC and stuck it on the rear which was easier in the rush.

Right vs left was 656 vs 704. Nothing I can do about that really without adding 50gm weight to the left. I could move the transponder over.

But what I am not sure how to interpret is individual wheel weights. “Looking “ at the car from the rear they were

250 410 front

454 246 rear

Left right

I guess I expected more equality. Car was setup last week for the non run BTCC and so has zero tweak.

Without having 4 decent scales under each wheel there is a lot of room for inaccuracy here but I would have thought the relative left and right readings for the individual axles would have been reasonable and the total weight from the 4 figures is within 10 gms of the total car weight given by the scales.
Any views on whether I should be concerned about what I am seeing here or whether the method used just invalidates it all.?

Hey Pete, this might be slightly related.

I made my car rear heavy when I first got my T3 to take away some of the super steering it has, but found in damp conditions outside that the rear would then oversteer on corner exit and the car would spin out, making the weight distribution more equal helped on corner exit. Which is weird because I would have expected the weight on teh rear to give constant understeer....

long story short, I try to run mine so it feels balanced in my hands front to back / left to right... ive not tried a true balance but I know Simon Crabb did this when he had a TC.. Ill check with him to see if he found an improvement.

Hi Reuben, I have picked up your point and started a new thread.

My question here though remains, does anyone find the magnitude of the "discrepancy" with my individual wheel weights surprising?
