i need full suspension kit for 911 cab to handle the power on curves and high speed , is it possible to get a good handling out of cab models ??

 

Yes of course it is possible; $$$ will make anything possible. :-)
If you like lowering springs, I would recommend either Techart or GMG springs; these 2 springs are stiffer than the H&R spring and therefore better at improving handling. GMG is probably the most popular lowering spring on this forum and there are many happy owners. I would suggest adding GMG sway bar.

If you mean complete coilover by "full suspension kit," then I would recommend Bilstein Damptronic as a perfect beginner's level suspension mod. This is the most popular coilover for the Turbo, maintained PASM compatibility, made by same company that does the OEM suspensiion, and like the GMG springs, make many owners happy . Again I would suggest to add GMG sway bar.

Both GMG and Bilstein Damptronic are well known entities on this forum so the improvement is without doubt. Stock car cannot compare with this improved handling.

Get the most experienced tuner possible to install , do not buy used suspension component, and buy only from authorized dealer. Installation error is responsible for majority of suspension problems; ask specifically for background and do not let any inexperienced installer or first timer touch your car. There are multiple threads on suspension on this forum that you could search; or you might want to start with the first page of Bilstein suspension link in my signature below. Good luck and have fun.

 

is it suitable for cab models??

 

Please explain, then maybe I could answer better.

1. What is it about being a cab that causes you to ask about suitability? Flexible chassis?

2. Suitable, as far as what apsect of driving experience?

 

as i used to have 997.1 tt coupe it handles much much better and when i checked kw they much more options or choices for the coupe and only the v3 kit for the cab

 

I have KW Clubsport and I am quite content with it. I had Damptronics on my previous one, which were also very good.

 

To best of my knowledge, the suspension of coupe and cab are the same, so I assume you are referring to the chassis flex inherent with convertibles here?

To answer your other question, yes, it is possible to improve the handling of a cab, by using suspension with stiffer springs. But this won't do anything for the chassis flex itself. The car will drive better and handle better, and feel tighter, so yeah, subjectively it would be better, but not because of less chassis flex.

Second, for the chassis flex of a convertible, I don't know if there is any reason for any particular suspension system to be "better" than any others. Intuitively it would probably be a good idea to stay away from ultra stiff stuffs like JRZ and Moton, but beyond this I would pick the after-market suspension system based on its characteristic and features.

 

I'm going to guess that most people do not drive a car hard enough off the track to notice chassis flex...but I could be wrong. There are a few companies out there that have developed braces that mount in and out of cabs to increase chassis stiffness...but again, it's probably overkill for most drivers.

 

thnx guys , i have already installed H&R SPRINGS and i will look into KW V3 and bilstein ..

 

I am very happy w my PASM bypassed KW V3.
Also a quick note. The peoper set up (alignment and corner balance at a minimum) will go a long way to make your new suspension set up work for you. Don't skimp on this portion of your build.

 

what makes you disappointed with the HR springs?
