I'm interested in getting the RB springs to improve performance, but I've got a couple issues.

1. They say that it lowers the car 1". I'm concerned about the ride hight causing the car to bottom out. (Daily driver) Is there anyway to prevent it from being lowered a full inch?

2. The car would get lowered in relation to the tires. I'm concerned that going over a bump the car would rub the tires. What can I do about this? Where abouts are the bump stops set? How much am I limited in the future when replacing the tires/rims (say I want to go wider)

Thanks guys.

i dont' think that 1 inch is too muhc

some ppl lower their cars more then 2 inches...which i dont' see the point but how big are your tires??

I have springs that lowered my car 1.6 inches from the stock specs. I don't bottom out. I just have to be careful not to rip my gigantic mufflers off (again).

Thanks for the replies,
I working on waring out my current tires. I'd prefer to keep the stock 16", 55 hight. (unless there's a good reason to switch) I'm currenty 205, you can do 225 at all four corners max without doing anything radical, correct?

None the less, any ideas on how to reduce the change?

The biggest problem with a lowered car is camber.. bad camber sucks.

I have RB springs with KYB adjustables and I love the feel of the car. It gives the car a great feel and look without making the car ride harsh. It isn't a sedan like ride but thats not what we are looking for when we buy rx7s now are we?

I was actually hoping for harsh.

I appreciate the replies, but my main concerns are still yet to be answered...

All depends how harsh by how you have the shocks and struts set to

I have the RB springs and I love the look and feel of them. The car has never bottommed out and the tires have never rubbed.

You have to remember that when you go to an aftermarket spring like the RB ones, they are alot stiffer than stock. Even though you have 1" less travel until the car bottoms out, it takes far more force to compress the spring - making it harder to bottom out. I'd make sure that your exhaust isn't hanging low, 'cause that will hit first.
My tires (205) have never rubbed ever - no matter where/how I have driven - even though there is almost no clearance with the strut. I don't think that this is a result of the springs though.
If you go for new springs, make sure that your struts are ok, 'cause if they're worn out it will exagerate every problem.
The ride is stiff, but smooth. Turn in is very precise, and quick transitions from side to side are great fun.

I personally ordered some tein full suspension and I will lower it until the fender is about equal to the top of the tire. Personally I dont go by 1, 2 or 3 inches. I just lower it the amount for better handling and it looks good. Btw, in relation to the question, you dont have to worry about bottoming out. 1 inch lowered is nothing to worry about. You shouldnt have to worry about the fender hitting neither because you will still have plenty of space between the fender and tire. Only when the fender is right above the tire is when you worry about the fender hitting when going over bumps. You should definately have enough cushion and like mentioned before the spring rate and shock stiffness will matter. So if I lower my car all the way until its equal with the fender I wont have to worry about the tire hitting the fender neither because the spring rate, and the shocks will be set stiff enough so that the car will not bounce dramatically when I hit a bump.

The stock springs on a car with 75k+ will already be sagging (settling) close to an inch already. I put Eibachs (3/4 " lower) in my car and it sits no lower than it did before I installed them.

You're making me feel better with the experiences shared, but I'm still worried about nasty curbs. There's one near by that I drive up and I've seen a C5 scrape severly when creeping over. I've seen higher cars than mine come damn close.

I'd still like to know about any methods to prevent the car from lowering so I can evaluate from there.

Pretty much the bottom line is if you want factory ride height youll have to buy aftermarket coilovers so that you can raise it up all the way and still have a stiff spring rate. If you buy LOWering springs, theyre gonna lower your car. No way around it.

so when you lower a car you should adjust the camber, why do you get bad camber when you lower a car?

Because it puts stress on the suspension(contol arms etc,). Plus your lowering your center of gravity and the factory parts werent meant for the car to be lowered therefore the tire will lean inwards towards the top because of the weight of the chassis.
