After running on 19s for the past 2 years, I found some 03' stock 18s, and threw them on over the weekend. What a huge difference in ride quality/handling. My car has been lowered and running the Formula Dynamics springs, but with the 19s, it was rough.

I can't stop driving my car now, the best I can explain is that the car feels like a snake while taking twisty roads.

Most people that go the ultra-low profile/big wheel route don't realize how much the ride quality can suffer. The 18's with 35's aren't going to roll much at all, but what a difference in real-road drivability. They might look cool, but...

Same thing with my IS. I opted against the 18" wheel option because the 17's handled supremely well (and supposedly there was some issue with compatibility with the AWD system). The 18's looked better, though.

The closest analogy is chicks in really high heels. Looks nice, but they won't be running comfortably in 'em...

For you older guys like myself, it wasn't too many years ago that the car mags were referring to 18's as "rubber bands" on wheels. How things change! :D

My '06 GS with 19" wheels and matching 35/30's helps me count every pebble on the way to work. Didn't realize there we so many of 'em.

i dont want to trash Formula Dynamics springs, but i remember one post claiming the ride was somehow improved and is less rough than stock (lexus was the word if i rmb correctly. (not easy to forget as this is an unusual word in this forum). i m too lazy to search but if someone has time please find that post.

so what is the point of lowering with FD springs when you have to go back to 18"??

(okay i found the post:

Hey Guys,

I was Formula Dynamics first customer for the sport lowering springs. I had previosly lowered my car via collar adjustment like so many of you here have done before and was discouraged by a harsh ride and yet still sub par handling with undesirable body roll so I put it back to stock right away...

Not only does it have ZERO BODY ROLL, but it rides smoother than stock height/springs ((askmywife)it is as smooth as a lexus over rough pavement.

i am confused as to what to believe.

Well M!, looks as "roughness" is a very much subjective appreciation... :rolleyes:

But must admit, as you say, that demoe's point throws-in some Qs on butter-smooth ride claim behind the FD springs. Not saying they do not improve the ride (have not installed/tried them) but...

i am confused as to what to believe.
In the stock configuration on my 02 Spyder, I found the car had the following negatives:

1. body roll -lots of it.
2. on uneven, wavy pavement, the front end would bob up and down like an old Caddy.
3. handling was smack dab in the middle between a sports car and a lexus.

Enter Formula Dynamics

1. very little if any body roll
2. the rebound on wavy pavements was shorter/stiffer, lost that Caddy bobbing.


With 19s.

1. as DeaneG said, you could count the number of pebbles on the road.
2. I could have been used as a consultant to CalTrans as I was intimatley familair with every pothole.

FD-with 18s.--

1. I think Robbs Lexus comment has to do with rolling over rough pavement, stock, the car would have a tendency to be too soft and therefore bottom out, with 19s, it would be more like an explosion in the cabin. W/the FD springs, you can drive over the same rough pavement and almost not notice the imperfections, like a Lexus.

I guess it depends on where you live, as I have spoke to 4 random people who live in the Bay Area who all felt the stock setup to be "too soft". We have this problem in the bay Area, not to get into social politics, but we spend a bit too much money on social programs which leave little monies for things like re-paving roads....so our cost of living here is one of the highest, but we have 3rd world roadways.

Demo give the GS a try

Demo we shold go for a run in the GS and see if you like the over all changes from the coupe. As you know I went down the lowering path 1 1/2 inches on my old coupe, car road like a truck, slamed over every bump. But the GS seems to do well across the board, still get some garring over bumps but not as bad as the lowerd coupe.

I love all the dialog, I'm sure that many of our customers can report their own personal experiences here.

Tires are a very import part of your suspension. The 18's roll too much for me but then again I don't drive the car daily so when I do go out for a ride, I'm looking for the sport feel. The springs work well once your skyhook learns the new ride height and spring rate. Changing tires will definitely give you a different feel.

I drove a Lotus Exige S this morning and can't believe how stiff that suspension is. I went over a bump that we drive over all the time in our GS with 20" wheels and I thought I broke something in the Lotus!

In the end I think it depends on how much you drive the car. If it's a daily driver, the 19's and 20's may be more than you want. I personally like the 19" wheels the best overall.

it is very strange for GS owners then, because most of them use them as daily drivers and they come stock with 19". so perhaps FD springs are 'may be more than you want'.

Not sure it is how much you drive the car. Maybe it is more how old you are. When I was 22 I was driving a 240Z that had been campaigned nationally in autocross. Most of the bushings were Delrin but some had been changed to aluminum. Even the smallest pebble felt like hitting a curb. Then again, the handling was unbelievable. You could come into a corner at 100, hit a break to negative camber, fly sideways 4-5 feet (not slide but almost air born), and finish the corner on the gas. That ride was OK then but I wouldn't do it now. I want good handling but a reasonable ride.

This is exactly what we went for... we run 20's but I agree that it would increase ride quality on 19's or 18's.

Our springs are meant to improve handling and safely lower your car, without making the car too harsh for the street. We have customers who ask for even stiffer springs after they install ours and we can produce them. It's all about personal preference, I don't enjoy driving the car with the stock springs, it has far too much body roll.

Endless search for ride quality...

Great post. I find after lowering my Spyder that the rear suspension is very compliant and balanced now. I felt that the rear shock pre-load was not in the sweet spot of the shock stroke. After lowering the fronts, I still feel the overall ride quality is better than stock, but the fronts do feel too soft overall. I find myself liking sport mode for the ride quality better than normal even when I'm seeking comfort over sport.

FD-> As the expert in this area, can you speak to the spring rate you chose for the FD springs, front vs. rear.

I'm sold... I was thinking of moving up to 19's, but I'm convinced that the 18's are probably better all around for my driving style. I'm interested in adding 10mm to the width both front and rear when I get new tires. Any opinions?
