Hey Moderators if you want to close this post and put it with my other one that is fine. I just had a second question that I needed some answers to. Thanks. OK here it goes. If you were going ot lower your cars what would you do, buy the springs, buy the clamps or Cut/heat your springs or donor springs. Also what is the measurement for cutting the springs. For example if you cut one full coil off the spring does it lower your car a full inchs? Same with heating, if you heat it them push them down an inch does that lower your car a full inch. Thanks for the help guys. ALLLLLSSSSSOOOO (hehehe) If I lowered my car what are the biggest rubber rim combo I can get, Right now I have 235/60 R15s but I want to up it to 245/50 R16s. Would that new combo rub when I turned the wheel? Thanks

I would buy the spindles & the rear spring package.

The reasons:
1) it does not change the Geometry of your front suspension.
2) heating the spring weakens the springs, & could cause them to break prematurely, making it dangerous.
3) using clamps causes unusual stresses in the spring as well that could breakage..

I would do all springs.

1) Mainly because with drop spindles you will still have the "relatively" soft springs and you will be much more prone to scraping. Lowering springs are stiffer, thus this is not nearly as big of a problem.
2) The wheel geometry can be adjusted at your local Midas etc. for less than $40.
3) From my experience the clamps do absolutely nothing. And I would definitely not chop the original springs, mainly for reason #1.

For wheels, I don't know what is the biggest, but I have 17x9.5" with 275/40x17 all around, and there isnt too much room to spare. Could go bigger in the back, but up front that's close to max.

Im with Okfoz, I did the spindle/spring package. Also running 245's all around. Expect some rubbing, esp. w/ lowering and bigger meats, but absolutley happy.

I went with the energy suspensions lowering springs, did all four when did new shocks and struts, The car sits much better now and the handeling difference is noticable. Although with my newly installed 3" exhust system I only have about 1 1/2 to 2" of clearence under my cat.

 

I was going to use the drop spindles.But they will not work with my 1LE brake package.I am probably going to do some sort of spring mod?

you do know that cutting the springs both shortens them and increases the spring rate (stiffens the springs). In fact, it is recommended that you use springs from one of the non-performance suspension setups because WS6 or 1LE springs will actually be too stiff (obviously this depends on your tolerances, but a guy I know who builds some serious cars and whose last daily driven 01 SS ran 10s, just lowered his new trans am by using cut V6 springs.)

 

Springs notlow enough without disturbing geometry? Spindles with saggy stock springs?
DO BOTH! Lower with Belltech drop spindles and Eibach 1" lowering springs. A 3" fron drop seems excessive, but if you have a Formula like me, you wont scrape the front bumper (Just the airdam) and you will still have sufficient ground clearance go SLOW over speedbumps.
