i have those ebay coilovers on my eg coupe, they're good at first then after u drive them for a short period of time, they're straight garbage! They're bouncy the mess up the rest of your suspension and if your lower to muck n u hit a pot hole, not only will u bottom out, but u will bounce for about a block lol no lie!!!!
if you have the money i would go with tein, full suspension setup, or skunk2 for a reasonable price
