Anyone have approximate corner weights for a 2008-2012 roadster?

Looking at doing some suspension tweaks. TIA

Not to be argumentative... but I find those numbers a bit hard to believe.

The front to rear is exactly 35/65%, AND the left to right (in front and in back) are exactly even.

I don't have numbers other than what is posted in magazines, but I'd be a little suspicious of those numbers.

You are correct, they are a starting point, anyone doing serious corner weights would have scales for their car. But it will take out the spring height guessing assuming you are going with the 435/355 shocks. As the OP didn’t post their weight the rest of the calculations are never going to be better than front to rear.
the rear shock will be the one to watch out for, as no one has built a 3rd party shock for the Tesla and having a shorter closed length on the rear will result in wishbone/chassis damage as the rear weight will overpower what’s already on the market.

Has anyone measured the stock springs? Love to know the spring rates AND the Anti Roll bar thickness and arm length. TIA!

going through notes and came across these.
Shocks
Front 13.97 inch - 11.2 inch = 2.75 inch
355 mm - 285 mm = 70mm
Rear 17.12 inch - 12.79 inch
435 mm - 325 mm = 110 mm
Closed length is longer than the wishbone strike point. Lotus had 40mm extended eyelets on Nitron shocks to increase rears.
roadster stock 600 front
900 rear
Elise S2 860 kg 425/550
Exige V6 1176 kg 550/1100
Roadster 1260kg + 37% S2, +6.7% V6
Nitron recommends 550/700
Extrapolation would indicate 600/1200
Weight is 38%/62% F/R

Again corner weights would be set with the driver.
