Recently I upgraded from Tanabe GF210 to Tein Flex.
Wow.. Even I haven't tuned the suspension (allignment and corner balance), I definately feel more confidence.

My car's main duty is weekend track days - non competition, weekend drive, twisties roads, some AutoX.

I've done about 6-7 track days for the past 2 years so far w/ my old setup GF210 and I'm wanting to have a good setup for this Tein Flex that I just installed.

Please share w/ me the following:
1. Main use of the car.
2. Brand and Type of Coilover.
3. Front and Rear Camber and Toe setting.
4. Front and Rear Distance from Center hub to fender lip .

Several questions:
1. What would be the best range for question #4?
I'm not looking for a slammed look just something functional w/o having to buy 6Gun Racing Ball Joint Extension Kit

2. Should I allign the car first prior to corner balance?
What do they do to the coilover to get the weight balanced?
Raise/lower by reopening the coilover from the hub and turning the bottom adjustment?

3. How about spring preload? Is this something that needs to be tuned as well?

I am really BLIND about coilover setup especially spring pre-load and corner balance so links, reading materials, advised are appreciated :)

14" in the front, 13.5" in the rear works well.

Have an alignment and the corner balance done at the same shop...

The flex have dual height adjustable I believe. The preload is affected by the height on the spring adjustment. Search for much more info. on spring preload. Again, search for all the other info.

With that said, I have the V3's by KW and love them. Best coilover I have ever driven on. I believe they are the best system you can get without spending big bucks on Ohlins or other 2 way coilovers.

the flexs height and preload are on different perches. so neither of them effect the other. i had my car aligned and it feels great. then for twisties i run right in the middle for the front dampening and then about 2 clicks softer for the rear, seems to help bring the rear out a bit with the extra weight transfering. but i also have hotchkis sways so that setting may not work as well for you.
