Good call Larry !!! It's not like the RS shocks have adjustable dampening like motons...

 

You guys are completely missing the point.

What about suspension mounting points, geometry, and range of adjustability?

For example, the RS uprights are quite different than the normal GT3 ones...

The GT3-RS has been driven to a 7:43.5 with only 380hp. What does that say about the handling???

 

Exactly.

 

I'm not...I realize the RS suspension geometry is superior to stock GT3's...Not sure if it's a worthwhile investment for a car used the majority of the time on the road...but then again....

 

Tyson, I wasn't missing the point either. I agree that the suspension has a better race oriented geometry, and works better. I just questioned wether or not it had more adjustments than a standard GT3 (which it doesn't).

 

I was obviously trying to make a point. Hell, my WRX with stock suspension provides that just fine.

Better investment than a CF wing...

 

Larry,

Are you sure about this? I realize you own a GT3 (I'm not yet a P-car owner) and undoubtedly know a lot about your car and the marque, but I seem to recall that because of the different geometry, more suspension adjustment is possible. Is this incorrect (it would seem to make sense)? I'm not trying to get into a battle with an owner, just trying to provide help/additional information where I can, as well as increase my knowledge.

By the way, awesome car.

No offense taken. I think that multiple terms are being flung around in this thread, and there is some confusion.

The geometry of the suspension, that being the angles of the control arms, and other members in relation to each other that determine the arc, camber and toe of the wheels as the suspension goes through it's range of motion is set by their pivot and attachment points.

The adjustabilty of the suspension, that being the range of static settings for camber, caster, toe and ride height are separate items and usually determined by the method of adjustment and the amount of movement allowed by their design (i.e. the length of the slots for moving the strut tops, the size of the eccentric bolts for setting the toe and rear camber, etc.)

So an RS can have better geometry, whilst having the exact same amount of adjustability in it's suspension. I couldn't tell you that for certain unless I had them on lifts, side by side.

 

A pro suspension (JRZ doubles, special valving, custom swaybars, Cup drop links) would run almost exactly the same as the factory RS kit and would offer vastly more adjustability. The RS apparently has different (I assume Cupcar) front uprights and links, supposedly to reduce bump-steer because of the lower ride height.

Does anyone know the actual spring rates on the GT3 vs. the RS? Someone told me the U.S. GT3s run 250/290 lbs., which is astonishingly low-- I started with 600-700 on my 993 RS and wound up with 900/1,000, and the 993 Cups go much higher!

Anyway, back to the GT3... if the spring rates are really that benign (someone correct me with actual data, please), I would be inclined to go significantly stiffer for a club-race car. For the street and occasional DEs, stay with stock and save your money.

If anyone has detailed technical data on the GT3 RS, please IM me--been looking for it.

Damn Noel, you are a bad influence!!!

 

What do you mean by "run almost exactly the same"?

Why wouldn't you put in JRZ doubles WITH the RS uprights and control arms??? It's not one or the other... if you want best results, you do BOTH.

I'm even thinking of fitting these parts in my GT2.

 

I wonder if the mounting points for the control arms, ect to the chassis are the same??? I would expect the different Geometry might require some hole drilling/measuring???

 

The GT3-RS has been driven to a 7:43.5 with only 380hp. What does that say about the handling??? [/B][/QUOTE]

It says it handles well on that track.

 

It means it handles well, period.

 

ahh, I thought the Motons were a full coilover setup


does the RS have different sways, struts, etc?

edit: read through the thread more and figured out some of the differences. Thanks for the info guys
