i heard not to lower a redline. it will f-up the suspension. maybe if the springs were custom made for the redline, otherwise dont do it. buy new rims and tires, bigger rim smaller tire, but dont go bigger then the overall diameter of what are on there now. it will throw off the odometer, and i think the speedometer.
Yea the sprints will work but not the eibachs. My dad used eibachs and it had alot of problems, thats the scenario you probobly heard. But i havnt had any problems thus far with the sprints. Handles a lil better too! But i do suggest using the sprints, it really sets the car off.
