As said before . A RSB for a P11 is the best upgrade for suspension. The install only took me about 25 minutes. I took el caro for a spin around the highwat section where all of the on and off ramps are . The handling is amazing. On a close to a 45 degree angle i did 55mph. You could feel the force pulling in the vehicle . My friend piddled in his pants i think. Well an overview. For 105$ well worth the mula. I am still waiting for my RSTB from Enohand. But if i ever recieve that i will put it to the test again. :cheese: :cheese: LMK if anyone else from the GB has installed and drove. If they have the same opinion.
