Price is for TWO rear shock mounts, enough for one car.
With the suspension design of the NA and NB Miata, suspension travel is at a premium, and having enough travel is crucial to good handling and ride quality. As you lower the car, that travel is further reduced, so there is less and less room for the suspension to move before it slams the bumpstops. Folks often think high spring rates are to blame for harsh ride when they lower the Miata a lot with our Ground Control kits but lack of travel and slamming the bumpstops is the real issue. This is particularly a problem in the rear of the Miata and as a driver you are essentially sitting on the rear shock that is just inches behind your back.
The widely popular combos of running an adjustable sleeve and race spring to lower the car on shocks like the Konis, Bilsteins, KYB, etc. all suffer from almost no rear suspension travel on a lowered Miata, even with our short bumpstops.
The additional one inch of travel doesn't sound like much but when every millimeter helps, that is quite a lot.
Fits on most aftermarket shocks for the 1999-2005 Miata including Koni, KYB, Bilstein and Tokico.
These also fit the 1990-1997 Miatas but you MUST use the rear shocks for the 1999-2005 years to use these top hats in the back (due to length of the threaded shaft). So, if you are ordering four shocks for your 90-97 Miata at the same time, you need FRONT shocks for the 90-97 as usual, and REAR shocks for the 99-05 to be compatible with these rear upper mounts. If you are ordering a bumpstop kit to go with those shocks, get the bumpstop kit for 90-97 as the 90-97 kit includes the same bumpstops as the kits for 99-05 but also includes additional hardware that you'll need for the front 90-97 shocks.
YES these fit NA/NB Ohlins coilovers - add these to the Ohlins for the BEST riding setup possible!
These are NOT compatible with 949 Racing Xida coilovers.
Fits factory springs, standard-diameter lowering springs, and 2.5" springs as used in the Ground Control coilover conversion kits.
Recommended for the rear ONLY. Using extended travel top hats in the front can allow the tire to contact the inner wheel well.
COLOR: Note the color has been updated. These are now anodized in black. No longer available in green.
Nice parts. Worked just as I hoped. I am running Koni Sports with FM springs. Rear ride height with FM springs was a little too high at 14" and the car still was on the bump stops quite a bit. I was able to cut one coil from the spring and add these extended mounts and still make up some travel in the rear. It now sits at 13" and has plenty of travel.
