RPM Street springs

[JaxJeff]

Does anyone have the RPM "street" springs and if so has anyone used them on the stock shocks ? I would like to use the springs only for now.
Also in general with a 1 inch drop in front is it nessesary to adjust camber ?

I'm sure they'll be fine on the stock struts for at least a while. You should always get an alignment after dropping your ride.

I have the RPM Sport Springs which have the same spring rates as the Street but spec'd to only 0.5" drop. My actual drop was closer to 0.75" front and rear. My front camber ended up at -0.5 deg. I don't have the before data so I can't say how much negative camber I gained but it seems most folks with RPM springs are ending up around -0.5 deg so you can probably expect similar with Street.

Thanks guys ! so when you say ended up with 0.5 deg camber that is without doing any adjustment right ? Thats what i'm trying to find out is if I need to get camber adjustable ball joints for the front with a 1inch drop ??

The problem with the MS6 is that it doesn't have enough neg. camber from the factory and there's no adjustment. I had my stock alignment checked and had virtually zero camber up front. My goal is -1.2 to -1.5 deg. for improved cornering. It looks like most people are only seeing around -0.5 deg. from the RPM springs. So, I'm installing the adjustable ball joints along with the springs this weekend.

That's right, no camber adjustment with front (couldn't do if you wanted to - there's non-adjustable). Only thing I did was swap the springs.

The decision of whether you NEED adj ball joints depends on what camber you want to end up at. If neg. 0.5 deg is what you want, then springs are all you need. If you need more neg camber, then adj ball joints are your only solution.

For me, I'm going to run with the neg. 0.5 deg for awhile and see how it works. Aside from handling, one of my key indicators will be whether the tires continue to wear faster on the outside shoulders like they did stock.

EDIT: IMO, the only real benefit in terms of time or cost to do the springs and ball joints at the same time is that you only have to get one alignment instead of two.

Ok cool thats what i was trying to figure out ! If I HAD to adjust the camber after springs. I'll see how it feels without doin ball joints. I drive aggressive only sometimes ... its not like i'm auto crossin or anything

i ordered a set of street springs and should have them on in early february. ill let you know when i do if you want to meet up. jacksonville fl right?

yea they might cause some negative camber which will cause your tires to wear on the inside faster. if you dont autocross, i would try to avoid this because tires can get pretty pricey.
