Lantley was right on the 6 inches being an awful lot. I ended up going with 4 inches instead. The fabricator talked me into blocks instead of a subframe. He said 4 in is the max he would go with blocks and when it is time to sell the FW, it would be much easier to return to its stock height.
He didn't just put in 4 in blocks. He did some kind of cross member and upgraded the U bolts. Anyways it saved me a couple of bucks and it pretty much leveled out my FW. Now the only problem is my 15 inch wheels look dinky. Guess its time to go wheel shopping now.
Let me know if this question is for another thread, but how big of a tire can I safely put on my 15 in wheels? I now have 225/75-15 tires.
