PART NUMBER: 61-3523
The Hard Dog M1 Hard Core Rollbar is designed for the serious SCCA Solo I competitor that wants to maintain a dual purpose Miata for street and racing use. The "Hard Core" model refers to the larger 1.75" tubing used, in comparison to the 1.5" tubing used on Hard Dog's Sport bars.
The M1 model is officially listed as fitting 1990-1997, because those years came standard with plastic rear windows, and this bar is not compatible with the glass rear window found in NB soft tops. However, this bar will fit all 1990 - 2005 Miata chassis when fitted with a plastic rear window convertible top. Not compatible with glass rear window soft tops. If you have a glass rear window in your soft top, look to the M2 models.
HARNESS BAR
Single and Double Diagonal versions of the M1 Hard Core roll bars come with welded in harness bar included.
X Brace version is NOT available with a harness bar, and must use a bolt-in harness bar sold separately on our site if a harness bar is needed.
Features include:
* Full interior width
* Complete use of soft top
* HARD TOP Version allows use of a hardtop in addition to still working with a soft top
* Durable black powdercoat finish
* Constructed of highest quality 1.75" diam x .120" wall 1026 alloy drawn over mandrel tubing
* Laser cut 3/16" mounting and back-up plates
* Complete hardware kit w/ grade 8 bolts
HARD TOP OPTION:
Hard tops restrict the space inside the Miata a little bit more than the soft top does. Therefore, the the Hard Top version of this bar places the main hoop a bit further back and slightly lower than the non-Hard Top version so that it clears under the slope of the inside of the hardtop.
Yes, Hard Top version clears soft top too. The Standard (non hard top) M1 Hard Core is the tallest design possible with a functional soft top but not necessarily the best choice for tall drivers using stock seats because of the more forward placement of the main hoop. We recommend the Hard Core Hard Top version for most drivers over 5' 9" with unmodified stock seats.

AVAILABILITY: While our site shows the item available to order that does NOT mean that it will ship immediately. All Hard Dog items drop ship directly from their factory to you. Inventory at Hard Dog fluctuates constantly with dozens of different bar models and configurations, and they are a small business that does not have an automated way to tell us if something is or isn't in stock at a given time. Some parts of the year they have inventory built up on hand, but there are many times in the year when roll bars and associated items are in high demand that they run out of most of the popular models and lead times can extend to 4-6 weeks. When we send your order to them, that's when they will let us know the estimated lead time for your order.
