Hi guys and greetings from Malta.
SPEEDO. I read the same quote on roll centres and tried it all out.
I raised both front and rear inner upper arm mount points, and found the car much more sensitive, with much less body roll. Remember that in my case, with plenty of droop I get lots of body roll. I decreased this by using roll bars both front and rear, but now that i raised the inner pivot points I fond the car even better. in fact it was so much more sensitive it took a bit of getting used to.
Regards
Joe from sunny Malta.
