does anyone know what the weight difference between the tein flex and stock suspension is? thanks!

I weighed mine at the time of install and they are virtually the same in weight. It's been over a year ago but I remember them being within oz. of eachother.

i agree, i just changed mine to the flex about 2 weeks ago and i held the stock one, and then put in the flex and they r borderline identical.

that type of weight add on is very crucial to performance and i applaud you for caring about it

wow, i thought they might be lighter than the stock units :(

They are not.

I mail mine from HK to Australia. They are 12.5kg a pair (front and rear). So I guess the whole package is 25kg.

No exact measurement sorry.
