Potential supply problem for Tokicos
The US distributor for Tokico shocks has recently changed. We don't know who the new one will be yet and it's quite likely there will be an extended gap in the availability of these shocks. We've purchased all remaining stock from the warehouse to give you the best service possible, but if you're considering a suspension package that uses these shocks you should order soon to avoid disappointment.
Update: we are sold out of the NB and NC versions.
^ I made a previous post that the Racingbeat are too soft for the drop. It could work for DD, but if you hit some pothole be prepared for the tires to rub the fenders. There should be more people that will chime in on this Racingbeat spring. Check the reviews on the miata.net if your interest on other people's input. There's different types of lowering springs review that might help you on deciding what you want.
Reviews on miata.net are usually based on a five-minute drive to the Social Security office.
^lol, I lost... oh wait, that's a different thread.
I think I might go for the HR. any opinions on those
Koni yellow should be able to handle FM2 springs.However, Billies HD would be a good match for FM springs. You can Also re-valve it to accommodate any spring combo.
