steve, from what i saw from the pics of the isc coilovers, i think that they were trying to make universal style ones and the rear shock shafts were alot longer then they needed to be making it not be able to lower much past stock hight as 32's needed to have the smaller shocks.
although, i had a small problem with a product from them and when i told him he was happy to exchange the product and even brought it himself to the workshop. i was happy with the customer service!
