Well I just talked to him...they have no inventory till the 25 of Oct and the impatient man that I am ordered the TVS kit since he had 3 in stock

Perhaps if you PM him maybe he can do something?

 

I just ordered a set last night...

 

hahahaha...are those the tanabes? Rome wasnt built in a day bud.

 

hahaha

the TVS kit is the Hotchkis springs and sway bar. Normally the price is actually more for the kit then if you were to buy the springs and sway seperately from stikiller. But since they were out of the springs, and I did want both, I got the price matched.

That is true..Rome wasn't built in a day, but I have a killer mod bug that has taken me by storm so I just decided to kill the bug...at least for now

 

Get some go fast mods, than try to squash that bug. Not possible.

 

I'm sorry, but I don't buy the spring rate analysis and the resultant "bounce" affect between stock springs and the Hotchkiss. It appears that the Hotchkiss have similar spring rates (plus or minus 5 lbs) and won't make a bit of difference in the so called bounce effect. Granted, the car will be lowered and may lower the center of gravity which may reduce roll if the roll center is reduced.

The shock valving on the RS and GSR are on the stiff side and a slightly (10 to 30%) increas in spring rate would help handling and cornering by increasing roll stiffness.

Reducing ride height will affect camber and toe a lot.

 

So which spring do u recommend?

 

You dont have to buy anything...drive a car with stock springs then the Hotchkis, youll feel no difference, especially in overall bounce. You cant say that for the Tein Stechs.

Are you trying to say there is a better spring? Id say the Hotchkis springs are the best hands down. Perfect drop, no sag, no bounce, stock like ride.

 

BBenavitz from another computer;

If you want stock ride quality with a lowered look then the Hotchkiss may be the right choice. As I mentioned, a slight reduction in CG (center of gravity) may slightly help the handling by reducing the lever effect of a higher riding vehicle. My only problem with this is that you are reducing the wheel travel by 20% with no increase in spring rate. On a road course you may bottom out the suspension at one corner; say hard braking and turn in, and you may bottom out the front corner wheel which will then force abrupt, terminal understeer when the control arm hits the bump stop. On my old C5 vette GM went to a slightly stiffer rear spring for the Z06 because they found this was happening and the car would go into abrupt oversteer because a rear corner would hit the bump stops in aggressive cornering and acceleration.

IMHO, you could take the stock springs out and cut a half coil, or what ever you were looking for and get a lowered look with near stock spring rate for very little cost.

If you want more roll stiffness, lower CG with a lowered look for track purposes then it would appear that the Eibach's may be a good choice. As you know, the RS and GSR already have very stiff (in rebound) shocks. A stiffer spring like the Eibach's may be just the right ticket to get this. Why does the MR have the softer Bilstein shocks with the same springs? Better (read softer) ride quality which will always relate to less handling capabilities in transitional movements on a road course. When was the last time you heard a street car being prepared for the track with softer than stock shock rebound? Never. Also, any street car turned to race prep will add stiffer springs and shocks for better handling. You will also see them alter the length of the control arms to maintain the roll center when they use shorter springs.

The problem with all of this is we don't know how the roll center is changed with lowered springs and this is a very important element in handling. If you go to low the geometry of the control arms is altered and you will screw up the handling more than helping it.

The best bet for a better handling car is stiffer sway bars front and rear, stiffer bushings and a good alignment. The Eibach springs with about one inch of lowering may not be low enough to screw up the roll center. Good question for the Eibach engineers.

With all this being said, I still run the stock springs and shocks on the track with my GSR. I have gone to 1.5 degree neg camber front and rear with zero toe front and rear and the car is dead neutral in medium to fast corners. I would go with a little toe out in the front, but I don't want to increase tire wear.

 

BBenavitz,
How can you compare spring rates from stock to the Hotchkis when the stock is a linear rated spring and Hotchkis is a progressive rated spring?

 

The info I've found says the stock spring rates are F: 180lbs / R: 225lbs
Is this not correct?

And the Hotchkis are F:195lbs / R: 278lbs

So that is an increase of 8% in front and 23% in the rear. Granted this is taking NO progressive rates into consideration...

I guess the question is... is the stock suspension over or under dampened?

I 1st ordered the Hotchkis myself... but then changed my order to the Tanabe's.

Why the change?

 

It was a toss up before I ordered. Based on the reviews, I think the Tanabe is better for what I want out of the car, etc. And I figure I could allways sell or trade the Tanabe's for the Hotchkis if I end up not being happy with them.

i just installed my Hotchkis springs this past friday. the stance is perfect . not too low tho(still made it over our center post lift) . im overall happy with them. the car feels like it handles pretty much exactly the same. you dont feel the road as much as before, but its still not a caddy(which is a good thing). but to my suprise they are bouncier than stock.. not much but they are. there is a spot on rt.97 that has ripples in the road. i had a little bit of bounce on these ripples with stock, and now with the new springs the bounce has definatly been amplified. still not as bad as my koni's all the way stiff with h&r race springs that i had on my vee-dub . definatly livable. i cant compare them to other springs for the evo, but i do like them alot and think you will be happy with them.
