I drove my car today... I put on Mac rear lower control arms and tokico shocks... Also KYB quad shocks... I had ebay springs on it before... I went from 245 45 17 to a 275 40 18 also! And let me tell you!!! 100% worth the money!!! My rear end is so stiff and hugs every turn and wehen i hit on it with the 4.10 gears it hooks and goes!!! Rear lower control arms in my opinion should be one of the first mods! Along with the shocks... i will tell you how well the front is once I get the cobra brakes and tokico struts on up there!!!!
