I'm curious, how do you judge that the rear is too soft? Understeer?

Slight understeer and lots of roll at the back, confirmed by photos taken at a track day.
My engine is set very far back in the chassis I don't know if that makes it worse.

Hmm, I would think that since the chassis is rigid, the amount of roll is the same front and back...

So going to put the order in tomorrow with Gaz.

What I'm thinking is this.

G140/095B12-2
Front - 2x 8” 375lb 2.25”
Rear - 2x 9” 275lb 2.25”

How does that sound to everyone? I know its quite a bit harder but then again with the steel floor,18" wheels, full cage, chassis stretch, 7.5" diff and bonker 6 pot block I think it makes sense.

All advice more than welcome!!

Personally I would go for 300's at the back. But it's all a bit of a guessing game.

the only way you can tell is to calculate it form weights and shock ratio to be sure.
