Introducing the AST 4210 shock for the NC MX5
Chris Robbin's NC Miata, CSP Prepped for autocross use and still street driven. The perfect car to test the new AST 4210!
We don't do Group Buys unless its to kick off something new, and this is no exception. We've done a good bit of sales in NA/NB (1st/2nd gen) Miata shocks and have developed singles, doubles and triples with AST and some dealers' help. The NC MX5 is a very different chassis and does not have the extremely short rear shocks of the NA/NB, so it does not need a remote reservoir to have adequate suspension travel like those earlier cars. We've made 5200 shocks for this car and the RX8 (which share the same shock mounting types and lengths), but the remote reservoirs on the 5200/5300 design make for a pricier package.
AST 4200 shocks are extremely popular to autocrossers and road racers due to their performance, quality, cost, and lack of reservoirs
The longer rear shock on the NC allows us to spec a brand new 4200 model - a double adjustable monotube shock without reservoirs, but with a twist, and we are calling it the 4210. This design saves the cost of the remote assemblies and hoses, but still allows separate adjustment of compression and rebound damping. Most autocrossers and track drivers want and need separate knobs for these two critical adjustments, and the 4210 fits that need.
There is some additional technology AST is adding to the new 4210, namely the new Big Bore Nitrogen Chamber. This was a new design concept we saw at the AST headquarters in Holland a number of weeks ago and we've been looking for the right car to introduce this on. We will add additional pictures as these move into testing phase, just before full production. Basically the diameter at the bottom is enlarged compared than the main threaded body portion of the shock, allowing for more nitrogen volume, a large diameter floating piston, and more total travel within this shock body length. This 4210 technology is rolling out for the first time for the NC MX5, and it will propagate to other models soon after.
As with other AST designs, these Dutch built, high quality monotube have unmatched damping characteristics and can work equally as well on a track only prepped trailer queen or a dual purpose street/autocross car as well. We can valve them to suit any spring rate combination and they have a lifetime warranty.
The Group Buy details are as follows:
A typical AST coilover kit as supplied by Vorshlag (NC MX5/RX8 AST 5200 kit shown)
AST 4210 kit for NC MX5. Kit includes 4 aluminum-bodied, threaded coilover double adjustable 4210 shocks, 4 AST spherical top mounts, Spherical mounts on the bottom of the shocks, and 4 Hypercoil 2.25" diameter springs (you can choose the rates), and all spring perches needed. Tender springs (Eibach) can be added as an upgrade (for the rear).
Retail price: $3803
Group Buy Price: $2859 (this savings of $944 applies to the Group Buy folks only!)
AST spherical top mounts will be included into the Group Buy kits
These new shocks would ship in 8-12 weeks after receiving deposits. These will be some really trick shocks - nothing like this exists for the NC MX5!
If you want in on this deal please send an email to us at sales@vorshlag.com and we will discuss the deposit requirements and put you on the list. If we can get 15 or more people to sign up AST will make this production run, so spread the word. This $944 discount only applies to the Group Buy folks.
Thanks!
