Ordered H&R sport springs, should I do shocks at same time?

I know this has been covered in painfull depth already but I did a search and have not seen any info from those that installed the H&R which have the mild drop I want. 1" Front, 3/4" rear.

Anyone have expirence with these springs (or the similar steeda ones) with stock or any other shocks?

H&R claims that OE shocks will be fine and suggests I install the springs only first to re-evaluate the car for a while before adding the shocks.

Sounds like a plan to me, and considering I can R&R struts in a couple hours and do alignments myself usually, it is not too far fetched.

I just want to make sure that the car will at least be decent with the stock shocks. If it is going to be a bouncy, underdamped mess due to the slightly stiffer springs I might as well bite the bullitt and order some nice shocks as well.

Anyone have luck running mild drop springs with the stock shocks? Is there an actual handling improment or is it worse than stock unless the shocks are done too?

Any feedback would be appreciated.

I would suggest it if you can swing it.

I'm sure there's a long explanation of why you should but the bottom line is the stock ones weren't designed for a lowered vehicle and were most likely designed with the stock spring rates in mind.

I agree, if you can swing the extra cash, go for it. Might as well do it now. You know you're going to have to down the road. They're going to wear out much quicker than stock height.

Thumbs up

I have those springs and I'm very happy with them. I'm also still running stock shocks and struts for now, but I do plan to get Bilsteins eventually. The drop is just as they say - 1" F/.75" R. Here are a couple pics.

I have the H&R's (we're a rare group - hows it going RandyB ). I find the stock shocks/struts to be fine for my tastes. I have a daily driver and do a lot of highway driving, not many curves. The drop was mainly for looks, and I couldn't go any lower or I wouldn't be able to get in my driveway.

I also changed tires at the same time (to 255/45/18 KDW2's), so some of my experience may also be due to the tires having a shorter sidewall.

I found that the car is less bouncy, has less of a tendency to nose dive when shifting or braking, and does make the corners easier to handle. You do get jostled a bit more on potholes and cracks though. If R&R isn't a big deal (say even fun) for you, then I would just try the springs first and then decide.

Looks great, and it keeps that raked stance I like.

What did you guys have to do with the alignment?

Not much. My dad happens to be the front end tech at a Cadillac/GMC/Pontiac dealership. We did the springs and tires on his lunch break about three weeks ago. I still have the printout. We were in a hurry so we didn't baseline. My right camber is -.2 out of spec, nothing to worry about, left camber was still in spec. Left toe was out of spec -.30 and the right about -.10 out of spec. So we just dialed in the toe - He gave me a straighter toe than spec since I mainly do highway.

Here's some pics also. Took third place in the '79 and up Mustangs.

With such a small drop compared to other springs on the market, the stock struts/shocks might still be adequate. If you can afford it however, I think it is better to upgrade them to get the ride even better.

So far my my thoughts are to leave the shocks stock.

Right now I am a tad concerned about front ground clearance. I have the GT500 splitter installed and don't want to have driveway problems.

But the wheel well gap is annoying me at times so I am probably going to put the springs on and see what happens. With the thought that if the nose is too low go back to stock.

BuzzyStang, that looks great! What size spacers are you running front and rear?? That's the same look I'm going for, and I'm just about to order springs for the car. Figured I'd do spacers at the same time, but didn't know what size to order.

Congrats on the trophy, too.

I have the same springs and the factory struts work just fine. I wasn't looking for a "lowered" look, just wanted to get rid of some of the gap between the wheel well and the tire. These springs work perfectly for that! Surprisingly easy install too.

Btw, my bro-in-law is a designer up in Dearborne and I asked him why Ford made the car with such big gaps. He told me the reason is because Ford is concerned someone might want to put tire chains on their Mustang. Yeah. He thought it was stupid too.

Jay - I'm running the H&R 25mm (1") spacers. I almost think I could've gone with 35mm...but MRT Direct had the 25's on sale at the time.

Thanks Buzzy, I'll be ordering a set of those too, I guess. Makes the fanblades look really good on the car.

Looking into selling my Steeda Sport Springs for some H&R OE Sport.
The roads around here were paved by morons !! I have the Tokicos
and they are fine - set them 6-7 turns out for a better ride.

thanks. I don't imagine you have "before" photos with the same wheels?

Unfortunately no. I put the wheels on the same day I dropped it. I think I test fitted one wheel but it looked silly so I went ahead with the springs.
