I need major help!

1. if you have purchased coilovers, which ones, how do you like them, and most importantly are there any problems.
2. if you then purchased new tires... are they feathering.
3.which companies have released a decent priced system with dampening adjustment
4. is ity worth it to get the tien basic becauese the dampening is not adjustible?

Thank you for your help>.

 

Personally I don't have coilovers on my Z yet, but I do have them on my Teg (TEIN SS) and I they have been really great, no problems all satisfaction. I'm happy w/ the quality and performance. So I plan on getting the Type Flex for my Z soon mostly because of the EFDC option.
