Improve ride quality by getting your rear suspension off the stops! These extended travel top hats add almost 1" of travel compared with an NB top. Adding more free shock travel before contact with the bumpstops significantly improves ride and handling. Uses a rubber bushing for a noise-free ride. Compatible with all of our bumpstop offerings.
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.
Features of the RoadsterSport top hats:
- Comes with two sizes of metal bushing sleeves, and top/bottom washers; A set for 10mm shock threads, and a set for 12mm shock threads. This covers almost every aftermarket shock for the NA/NB Miata so no matter what shocks you have you will get the appropriately sized hardware for the bushings.
- Unlike some hats with studs pressed in, The studs in our hats are socket head bolts threaded into the hat from below. This allows you to swap the studs out for a different length if needed due to specific shock tower brace design, or similar.
- Comes with rubber spring seats for 2.5" diameter spring (the most common spring size used on coilovers/coilover conversions) - Anodized in signature RoadsterSport blue
Fitment Notes:
SHOCKS
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.
Recommended for the rear ONLY. Using extended travel top hats in the front can allow the tire to contact the inner wheel well.
