i just got a set of megan racing track series coilovers, i know theres a front and rear difference but, is there a left and right difference? or the coilover can be installed on both left AND right, cuz i couldnt find any markings. thanks

 

On the fronts some coilovers require to be on a specific side so the tab for the brake line lines up correctly. They should have marks on them somewhere.
The rears are interchengeable

 

Megan Racing coilovers are not like that though, so yes, you can put them on either side of a car. Flip a coin if it makes you feel better, but it doesn't matter, they'll fit.

4bolt-front
2bolt-rear

:P.
