need springs
 
i have a roush stage 3 front fascia. It already sits real low compared to the stock bumper. i put on eibach pro kit springs which lowered it 1.5 inches and now my bumper is 4 inches off the ground. i can barely make it over speed bumps and it starts to scrape going down my driveway. what are some springs that lower less than 1.5

FRPP B springs or F springs will raise you back up about .5". You should probably look at some poly-urethane isolators first. If you're still using stock rubber isolators or no isolators at all those alone will significantly help your problem.

Bullitt/Mach 1 springs on drop your car ~1" also. I think I will go that route once I get coil-overs since even w/ my stock front bumper, 1.5" is too much around where I live.

coil-overs replace the stock type spring entirely.

solved it. i went to summit racing and bought some mr. gasket twist-its formerly called knuckles. http://store.summitracing.com/partde...5&autoview=sku

just twisted those into the spring when it was lifted and dropped the car and problem solved.

one more real quick question. currently i only have the front springs in. i kidna like how it looks jacked up in the back. if i just left it with aftermarket springs in the front would that put too much weight in the front end and slow me down? and also overtime would it put any stress on the front suspension?

Yes, I'm aware of this, I should have put rear before springs.

Id imagine that would limit weight transfer. Either way, your springs will slow you down.

the cool looking front down, back up rake has a couple nasty effects on our cars. 1, the weight on the front increases braking effort on the front, along with more nosedive, more push in power-on corners and oversteer/looseness in braking. 2, the lack of weight on back reduces the already pitiful rear braking performance and on the street, particularly in the rain, reduces traction.

Those are my experiences and I didn't like the net effect. A little rake is cool, a lot is bad but still looks cool.

I have nearly the same problem. My mach I chin spoiler scrapes at times and I have bottomed out on speed bumps and the car wash rails at the local wash.

welcome to being lowered. I had a car wash rip off a part of my first set of matrix style subframe connectors.... grrr. you get used to having to make some comprimises for being lowered. You wash your own car, avoid speed bumps and turn into driveways from extreme angles.

soo lowering your car has some bad part to it, but are there more positive parts. besides it not being a 4x4 anymore??

r3dn3ck 04-23-2007 08:27 AM

lowering changes a LOT of things that were engineered to work a particular way. Problem is most people only change springs and so they end up with a crappy handling car with twitchy behavioral characteristics.

Yes there are a lot of bad things that can happen. However, if you spend the little bit of money it takes to do it right you'll have not only a better handling car but safer and more predictable results from any given input.

If you're going to lower it, do the shocks and struts, and a bumpsteer kit and rear lower control arms and caster camber plates. All those things put together (correctly selected... which means not based on price) will work in harmony. Do one at a time and you'll have to re-learn your cars handling with every single mod.

Not doing those things together doesn't mean your car is wrecked but it probably won't handle up to the expectations of the owner. Doing it right the first time is worth all the money in the world.

soo when i lower my car it would be best to save the extra cash and get like a whole kit from MM??

FEZ 04-23-2007 06:41 PM

You do not need to make all the changes put forth. It depends on different factors like how much you lower your car. Also the Maximum Motorsports 4 bolt cc plates use spacers to adjust your stock struts to full travel. I personally would not use the bump streering kit on a street car,and if you want good handling go with a panhard rod or Watts link set up as your rear suspension modifications.[ Drag racing suspension is not done this way].

r3dn3ck 04-24-2007 08:26 AM

you should do at minimum springs and struts and shocks and I think CC plates but you'll get a lot of debate about that. I would do the bumpsteer but if you don't do any serious driving (tracks, track-like roads you like to abuse, etc..) then it's a toss up. I don't like how the car feels without the bumpsteer kit on.

The panhard is a wonderful idea but I didn't mention it because I was only looking to give him a decent lowering on stock type parts. Panhard is a PITA to install for newbs.

Save up and do the triple play. Shocks/struts, springs and plates. after that if you aren't satisfied then move up a level.
