this may be a very generic question but i searched and didnt find anything i was looking for on h-t search. my friend has a del sol that he has tokico illuminas on the rear and he put coilovers on instead of the springs that were on it. my question is how low can he go on the tokicos without blowing them? they are expensive shocks and i would hate for him to blow them. i have no idea where to look for this on their website and besides i figured people who are running them have prob pushed their limits and might be out of the manufacture's specs. any pics/info would be helpful. thanks guys.
