Is it worth the $$ to go Tein flex A over Z

Looks like Tein flex is the best bet for the money from what Iíve read. Should I spend the extra and get the Aís or just get Zís? Should I spend the extra on other supporting parts? Should I keep springs and get bilstien shocks and save even more? We have very bad roads down here in south Louisiana. I have eibach springs now and itís pretty rough over large bumps and holes. Can somebody educate me more and help me make a decision?

Interested as well -- Indiana is really rough this time of year in terms of road quality. I love my Flex Z -- but i've often wondered about the hydraulic bump stop.

Are you on sportline or prokit springs?
Are you aware that it is sports car and it is going to ride firm in general?

Things that affect ride-
Wheel/tire size/tire type/pressure, what do you have? psi?
Travel, the lower you go the higher chance you will bottom out, the higher spring rate/firmer shock you will need to avoid that, which makes the ride firmer.
Shocks matched to spring rate.

Not 100% sure but think itís sportline. They were on the car when I got it.
Yes I know itís not a Cadillac nor do I want it to be. I want it to handle in the turns as well as possible without it being to harsh.

Rp1 17x9. Bfg gforce comp II. 245/45/17.(bigger and not exactly what I wanted but got a great price on them)maybe a mistake.
Since rims, tires and alignment, less than 1000 miles, it can get bouncy at times. Also rear shock is leaking. Didnít notice it before rims tires.

I could live with it as is but since it needs to be changed Iíd like to improve the handling as much as possible for around $1000

245/45/17 is a full inch larger than stock.
Sportlines are too low to have good travel, especially for the stock shock length.
They are also too much spring rate for the stock shocks.

Do you need height adjustment?
Do you need damper adjustment?
If no, I'd tell you to get some Bilstein b8 and have a simple effective setup.

The springs are supposed to be same as trd springs. The height is fine as is. I think itís a travel issue. I just donít know how adding b8 would compair to going with Tein. I have bilstien on another vehicle and really like them. If B8 would be as good or better that would be the route I would go.

We have our CSG Spec Tein Flex A coming in soon with complete revamped internals on the Flex A platform dialed in for street and track usage.

The ST coilovers are more street oriented and are made in KW's factory. Lot softer spring rate then either of the Flex series coils. I do like my flex Z's, but my car is a 3rd vehicle and my roads are not really that bad.

Mine is a 3rd, 4th if you count the wifeís vehicle. I do plan on trying out some tracking soon also. I certainly donít want rattle my teeth out race car feel but I want more handling than comfort orientation. I know with the Flex I can adjust but would likely leave it close to stiffest setting.

Both FLZ and FLA will drive/ride better than stock dampers on lowering springs.

I am Tein's development driver for the FLZ and FLA, as well as the CSG spec Flex A. Please feel free to ask any questions.

How does the Mono Sport compare to these, in terms of tracking?

FLZ and FLA can be, but are not meant to be tracked. The CSG FLA is designed to withstand extended track use. The MonoSport can also withstand track use, but it's apples and oranges, as it's a completely different design (monotube).
