ONLY for use with an 1990-1997 Miata lowering spring or stock 1990-1997 springs in conjunction with 1999-2005 shock hats Made from high-density Shore 95A urethane. Nearly solid composition that will still isolate noise Will work with any 1990-1997 Miata based 3.25" spring (OEM and aftermarket lowering) Pair with our bump stop kits for a great upgrade of more suspension travel, albeit with OEM suspension geometry, or pair with our bump stops and aftermarket lowering springs - such as Tein S-Tech - for a slightly lower, better balanced, and firmer ride.
Urethane Spring Riser for 99-05 Miata Shock Mounts
Miata Spring Risers
20945646 - PN-A-730
These spring risers are made to offset the lowering from substituting an NB mount in place of an NA mount with the same spring length. When upgrading from OEM NA to NB shock mounts, the NB mounts will lower the car about 3/4" due to the spring mounting surface being higher up. If you want to upgrade to NB shock mounts to gain suspension travel, however keep your suspension geometry the way the factory intended it to be, you will need these risers.
Availability: Normally In-Stock
A great way to lower your 1990-1997 Miata is to install a set of aftermarket lowering springs. The 1990-1997 Miata has an outdated shock hat design that limits the shock travel however, so upgrading to a 1999-2005 Miata's shock hat will provide about 3/4" more shock travel - however - this will also lower your car another 3/4" from where it sat with the original 90-97 shock hats. This will essentially "slam" the car and provide very little in regards to shock travel, which means the suspension will be riding on the bump stops constantly. If you would like to install the NB mounts on your NA using stock springs, you'll see a 3/4" drop just from the mounts. If you have lowering springs already and install the NB mounts, you'll see an another 3/4" drop from the mounts in addition to your lowering springs. This is too low for good performance, so installing these risers will allow you to get the benefit of additional shock travel via the NB mounts, but without "slamming" the car.
