I have a chance to buy low mileage megan competitions for a low price.

Megan sells different Kg springsrates for the coilovers. BUT IT can only go 2kg +-

Meaning, if the front dampeners are for 12kg springs then you can only use 10-14 kg springs to avoid damage to the dampener.

They have under 1000 miles i believe.

 

I have driven a skyline powered 240sx on Megan streets and 235/255 RA-1 and was blown away by how well it handled and rode.

For reference my FC has been on JIC FLT-A2 and JIC FLT-TAR 255/275 NT01.

Springrates you need are going to depend on the tire grip (width/compund),vehicle weight, swaybar selection, aero downforce as well as the lowspeed damping characteristics of the coilovers.

That said, 12k and 10k are high springrates for an FC.

I just don't think they are 2000lbs FC on 315/335 A6 with 200lbs+ of aero downforce and no rear swaybar high- which would be one end of the extremes in a unibody body FC.

 

For 200+ dollars i could order 10kg front and 8kg rears- Still too high?

 

I would need to know what the rest of your set up going to be with these to even offer my opinion.

 

megans are junk, dont waste your money.
if you're trying to keep it cheap/easy, go with stances for all your "low n stiff" needs.

 

WHeels 17x9 all around with 245 or 255 sport tires or slicks. These megans, CAmber adjustments in the rear also., Stock sway bars, Stripped out a lot. Cheap scca car.
And by the way its too late i already purchased them. for 600$, Megan comps. 32 way. adj.
