This is a great question and one I have been researching for the last several months on this site and yotatech. According to the Lift FAQ sticky and lots of other posts on here the 7 wraps will give you between 3 and 3 1/2 inches of lift in the rear (a few guys seem to have reported even more). I am torn between the OME 906 and the LC coils - but am leaning towards the 906 because I want around 2 inches front and rear and do not want the big rake. I have read that several folks have swapped in OME springs in the rear after installing the LC coils to correct the rake. Finally, the 7 wraps are darn hard to find compared to the 8 and 9 wraps - at least in the looking I've done. I'd love to hear from anyone who has the 7 wraps with the tundra front about how much rake they have etc. b/c I would much rather spend 80 bucks on the LC coils than the 150 or more for the OME 906. Also, if anyone knows where to find 7 wraps that would be interesting info to have as well. Thanks! - as always you guys rock!
