It was the rating of the SC kit I bought from Roush. The rating has varied between 415 to 445 depending on when it was offered.

 

No disadvantage I can think of. I think Adj LCAs is the best suspension upgrade I’ve done (and I’ve done a lot) I felt the difference immediately. they will greatly reduce your hop and you will feel the difference when you accelerate from a stop...a lot less flex than the crap stock LCAs and it’s an easy install so you will save some $ on that. But I do not recommend you stop with LCAs. With the added power you need to upgrade plenty on the suspension. But remember sometimes you need mods for mods so if you lower and get new tires you will need adj panhard bar and camber plates or you will wear your tires down real quicker than you like. Also recommend adj shock/strut and a professional ALIGNMENT.

 

It may matter exactly WHICH upper/lower control arms. The ones with poly in both ends tend to make the rear end "looser" when it comes to hard cornering, and with that much power it's going to be pretty easy to get the car wanting to switch ends as it is. Poly/poly is OK for the straight line stuff, although this combination WILL tend to make the car ride more stiffly than necessary when only one rear wheel at a time goes over a bump or dip in the road.

Consensus for rear control arms on a car that sees street use with hard cornering seems to be poly in one end and some sort of spherical joint in the other.

Sorry to sound like such a newbie, but never been in a power range where it greatly affect my handling like this...

 

It sounds like you're getting too much power too quickly for easy throttle modulation. Maybe a tune that has slower throttle tip-in would help.

well my boost doesn't come in til about 3,000 but when it does hit if its floored i start to spin again... but i'm more worried about how bad the back end drops down... and the wheel hoping... I'd really like it to handle better in the turns... I really don't know that i want to lower it tho...

 

You need better shocks and better swaybars.... If you are ok with lowering spring will help too, but of the 3 they are least important (not un-important mind you).

Tires, not the issue.... I will scare the crap out of anyone here on my stock (nothing special) Pirelli's with how fast I can run my local roads. Do tires help grip? Yep, but grip isn't the same as handling, it's part of it, but not it.

You fix the hop with LCA's, but lowering it will also really cut (might even stop) the wheelhop as well.

 

Yup thats true. No matter how grippy your tire is, if car doesnt feel stable then theres no way you can push it further.

 

Will the ones i listed do the job?
