Im getting my rear suspension kit next week so Ill soon have to be considering front suspension options. Main thing I need to do is get new springs. I want a 1 inch drop to match my rear end, so should I get normal cheaper springs and cut them or buy 620 that are already an inch cut?Any other options than 620? I have 351W if it matters any

 

go with the 620's and you can always cut them down too. They drop about 1" 1/4", and taking another 1/2 to full coil out will bring the overall drop 2+". Performance wise, they are a nice rigid spring, cut or uncut.

 

Keep in mind that when you cut the springs, the rate goes up. May result in too harsh a ride. 620 are already pretty stiff. However, I think the general consensus is that 620's w/ the drop are the most commmon upgrade spring wise. They also make higher rate, I think 750?, but they are more suited for a big block. To much on a street small block. The 620's with a one inch sway bar, monte and export brace and gyb gas shocks will make a night and day improvement over stock. Might as well do the ball joints and bushings too and you will be all set up front suspension wise.

Good luck.

 

Just took an inch out of my stock springs, looks great and drives the same.

 

with significant lowering, dont you also have to be concerned with bump steering?

yes, that IS one problem i took on with cutting a coil out of my 620's.

In regards to the increased spring rate, yes it will stiffen things up even more to cut a coil. but I didn't notice any difference between the stock 620 and the cut 620's (cosmetically however, there was a HUUUGE difference...the car has a nice rake to it).

 

Im ordering 1" drop mideyes for the rear so I think Ill get the 620's that are 1 inch lower already. Hopefully that will be level out good and be even.

I saw them but they are 720's.Mine shouldnt be nearly that heavy though. The FAQ sheet shows 351 weight about 520. Also. my battery is in the trunk so that takes a little bit off the front.
