I have the meister zeta CRDs and am very happy with them.
while firm they are not too firm for our roads.
no point putting suspension on that’s so hard that you end up arriving at a track day with a broken back!!!
I paired the zeta’s with the IL motorsport 30%stiffer antiroll bars AND I added all the chassis braces.
my car can now out corner a 60grand porshe
here is my project thread with all the details if you want to take a look!
