Well I went ahead and ordered the 90/10 for the front and the 50/50 for the rear. But thanks for the opinons. For the springs would it be better to go with coil overs or stay with coil springs. I eventually want to put a tubular K-member so i would have to put coil overs up front but i am not sure about for the rear? If anyone could explain it it woulg be great. Thanks
