Caterham Chassis Limitations

[SimonRogers]

In my opinion, 22mm is way too much rake. 15mm should do it on a car with standard suspension.

Regarding the 620's. They are so much heavier than the quoted figures that I would reconsider my original spring rates to get to the optimum setup. However, these are much closer to my rates than the spec dampers and springs.

I may offend some but I prefer the equal front weights as a setup for road and sprint/hillclimb.
I don't circuit race but I see no reason to think it any different.

I would put my cars handling up against anyones as a comparable extremely confident of any outcome - views.

As above my rake is set to just 5mm.

Hi all,

I followed the senior members advise and readjusted my cornering weight by following Simon's advice.
Luckily enough all i had to do is take some turns off the rear driver side spring then put the car on the scales.

The figures i got where following.
Left Right
Front 138 121
Rear 163 142

The total weight is different to my previous but this time i used different scales.

I then put the figures in the website https://robrobinette.com/corner_weight_calc.htm and my figures coincided with the suggested "ideal" setup.
I cross checked my scales several times for consistency then decided to leave it as is for a while.

I havent driven the car yet and do not know which of the two settings i prefer yet.
I tend to like the idea of equal fronts as tested but need to test this setting for a while as well.
May be with a car like mine having a tired past it best suspension and a f**ked LSD this setting is more even.
I will need to check and reconsider when cash will allow me to fix the above two.

Hi all

So a quick update,
I fitted some new tires 175/60r13 and tweeked the rake a tiny bit, i now have 12-14mm rake and the car handles so much better, it is much more adjustable and feels well balanced however i would prefer a lower level of grip at the front but still maintaining a quick, agressive turn in to "flick" it into the bends.
Is it better to raise the front a tiny bit 1-2 turns or reduce camber which is now set at 2.15?
Too much grip at the front makes it boring since it will always oversteer even if not pedalled well.

One turn on the raising plates was the answer. I do not know how much this affected toe because it did but the result is brilliant.
I even tested it back to back with my old elise and did prefer the the way the caterham handled which to me was a relevation
