I have often heard of the late model guys using 4cyl springs in their 5.0s for drag racing. I was wondering, could I use 65 6cyl springs in my 65 V8 mustang? What im concerned about is if the springs are too weak and can break. I figure the lower coil spring rate will lower the front end a little but thats fine with me. My V8 is actually lightened up with aluminum heads, intake, and water pump, along with headers, light weight starter and T5 trans (but I have the 40lb steel bellhousing which probably eliminates a lot of the weight savings of the T5). i just wouldnt want the coils to break on me. what do you guys think?
