Mounting Race Seats
I am going to be mounting a race seat in my car. I am having a hard time deciding on if I should buy brackets or making my own. I am planning on running sliders as well. I have looked for other threads and couldn't find what I am looking for. I also thought beeing a race prep item there should be a specific thread in this section.
I have found brackets from Sparco and Goodwin racing. Are there any others? Also If you have made your own Could you please post pictures of them. This will be my dd/track car so I will still be using the factory seats. I noticed that the Sparco may have brackets to mount the factory seat belt receiver. Anyone use one? Have a great day, Jared |
I have a braket made for side mounted Sparco's. They were included with a Sparco seat that a friend sold me and was made by Piper.
It's basicaly Sparco Sliders with tabs welded in the front, tabs to the rear (remove the stock humps and drill into floor and tabs for the seats. So everything is welded to the sliders with two cross bars welded under the seat to the sliders also. Seems simple I'm sure they charged like 400 dollars to do it though. |
It's pretty time consuming to fab your own brackets but. If you have the extra money I would just buy them if you dont... rainy day project
EDIT: I should be it can be time consuming depending on how tight the seats are. |
I made my own for the bottom mount of the Sparco Sprint V. I bolted the seat belt receiver to the tranny tunnel with backing plates.

This is what I was thinking about doing. I would love to see some pictures of your brackets. Was even thinking about just leaving them in the car and selling the seats. I would have to get some NA belt receivers if I do that.
Have a great day, Jared 1.8 Miatas' receivers bolt to the stock seats. |
This is the bracket I was thinking about getting.
Mazda Performance Parts: Custom Miata Seat Rail for RACE SEATS. They only offer one for the drivers side and I am going to be installing a seat on the p-side as well since I instruct and want my passenger to have the same safty equipment as well. How much different is the p-side mounting then the d-side? This one is made for the NA, but I don't think the NB is much different but for the mounting of the belt receiver. OG Racing - SPARCO SEAT ADAPTER BASE - MAZDA - Sparco seat adapter bases are designed to allow... Any thoughts os subestions would be help full. If you made your brackets are they simplar to the first one. Pictures would be great. Have a great day, Jared |
I made brackets to mount my Ultrashield seats on the factory rails.
Pics are posted on my cardomain page: http://www.cardomain.com/ride/810280/23 |

1.8 Miatas' receivers bolt to the stock seats. I'll get pics of mine, but I copied a guy's idea from cardomain. I'll take a look for the page. I used to 1.5" strips of 3/16" steel bolted to the stock holes, and the seat bolts to the strips. I used grade 8 zinc plated bolts to fasten everything, and used a 9/16" bolt for the seat belt receiver with 1/2"x4"x4" steel backing plate. EDIT: I copied this guy's, but I didn't use 4 pieces of metal. I was able to bolt just the two to the floor and the seats to them. I also contoured the brackets to drop below the OEM seat humps and follow the floor. I lowered the steering wheel with a 1/4" spacer as well.

Perhaps the single biggest safety factor in a crash is staying tightly bound in a seat that is well anchored to the chassis.
Two factors are of great concern: The seat and mounts need to be worthy of about 30 G's. 2nd, the harness and belts need to anchored both equally well and at the proper angles. Loads measured in Indy car and F1 crashes have often exceeded 100 G's with the driver walking (stumbling) away. That does not include overweight drivers. The last thing you want to do is die in a light weight crash. If you gotta go, make it a good one. Corky crashworthy design engineer in a previous life, but still very close to my heart. |
I just modified my factory sliders to the sparcos, it worked great but i feel the seats sit to high :(

I may just buy the goodwin bracket and slider for my the drivers seat and then fab something up for the passenger in hopes that a better mount will come out. Ever since I rolled my 2000 the safty issue has been the first thing on my list. Thank you all for sharing your custom mounting brackets and ideas. As corky stated there is an insane amount of force generated in an accident. So much so that it's hard to imagine. I can handle killing my self but I can't handle liveing knowing that I killed someone else due to my lack of prepairedness. Have a great day, Jared |
I've been a little lazy but I need to mount my seat. I think its going to be bolted to the floor. Like this: …and now I fit! johnkimballracing.com
Edit: and my buddy is helping me weld up a harness bar (3" exhaust tambien) to go where the seat belt tower was. Same seat and everything. The back gets bolted straight through the floorboard! http://www.johnkimballracing.com/wor...m-IMG_0168.jpg |
I do not know if you have your seats already but the Momo Start can be bolted to the factory rails (at least in an NB) with mild modification. They end up at about the same seat height as the stock seat, maybe a tad lower. This is what I did for my DD.
For the track car I have a Kirkey installed on a modified stock rail right now. It is too tall however so I am going to mount it to the floor using something very similar to what Turotufas and dgmoor shows above. |

Tex- I have not bought my seats yet, but have decided on the sprints. I will not be mounting them to any factory sliders since they dont just bolt up and they will sit too high in the car.
I want to get lower than the roll bar. My cage in my spec was much closer to the hard top so much so that it had to be trimmed in the rear above the window to fit on the car. I felt much more safe in that car than I do in my new one. Have a great day, Jared |
Jared, the bracket from Goodwin racing looks exactly like what my Spec builder fabbed for me for the drivers (although, he charged me $150 including the installation).
The biggest issue is getting low enough. I kept my humps, but, only because I'm 5'6", and can nicely fit under the rollcage. |

Here is what I came up with. I wanted the seat as low as possible so I did not use a slider. I also cut out the rear humps and bolted thru the floor with backing plates, I left the front humps in place. Cheers!
