Anyone know can I put the 05 S2000 both the front and rear stabilizer on 01 S2000?

 

Yep.

 

Yeah!!! Thanks, then I don't need to consider Mugen if the 05 Stabilizer will fit on 01 S2000. Coz the rate of rear stabilizer on 05 standard stabilizer is the same as mugen (25.4), and the front is just a little bit higher, but their price are just 2/3 less... thank anyway!!!

 

You definitely don't need to consider Mugen at all. The 04-05 rear stabilizer is so much cheaper. Smaller bar at the back actually benefit less oversteer and the driveability is improved.
