hi , is there any difference in running the new roll centre clamps then the old l1 l2?

dont realy want to spend the money if theres no difference..

thanks

L1 L2 rollcenter are in position R1 (shortest link) with 0mm

What are the equivalent to L1/L2 rollcenter positions in the new alu upper clamp?
Front: F1 + 0 mm and Rear: R1 + 0 mm
it's correct?

The manual of Xray says: R1=L+H roll centers / F1=L+H roll centers, does that mean L+H? a intermediate point?

The manual also says driver tips: when use 1mm on rear bulkhead use 4mm shims on the upright. But now with normal rear upper clamp i use L roll center and 4mm shims on the upright, and the manual says that 0mm on the new rear bulkhead = L roll centers, ¿?¿?

Thanks!

change between L i h is in shims (higher {H} or lower{L}) R1 or F1 is about closer to the center or wider
