PCI Adjustable Seat Mounts - Driver

I'm pretty stoked on this mount.

For anyone out there who might be doing the same research I did, I'm 5'10"-5'11" and I used this to mount a Thrash Racing Street Spec Alpha (in zebra, if it makes a difference). I had started out trying to use a set of SkidNation rails (which are well manufactured and I can't knock them at all), but because they're two separate side mount brackets and the mounting holes in my seat were a little... goofy, I couldn't get the rails to mount flush to the floor and still bolt to the seat.

With the PCI mount, the combination of the fixed base and the adjustable side brackets ended up being much more forgiving. While it took some patience and fine-tuning, I was able to get the seat mounted securely at a good height and within a comfortable reach of everything important (minus the clutch pedal, but I fixed that with Good-win's pedal extension). Would I want to go through the install process again? Not really! But, I think this definitely has more to do with the quirks of the seat than the PCI mount. I'd even argue that the fact I got the seat mounted at all is a testament to how well-engineered, well-constructed and generally well-thought-out this mount is.

As far as massaging the transmission tunnel, I didn't have a bad time with it using a small 2.5lb sledgehammer and the instructions do a good job of indicating the raised section that needs to be knocked down. Once the extra clearance was there, the base easily mounted flush with the floor.

Its a really quality product, but I don't think I would call this bolt in. You have to really bash in your trans tunnel to get it to fit. the instructions aren't very accurate with this either, saying "gently tap the front right with a small hammer", should probably state, "repeatable strike the front right with a 5 lb sledge" because that was the only thing I found to make any progress. Other than that, great product.

This is the second PCI mount that i have used on my miatas and it is a quality bracket. It works as it should and allows for a good bit of adjustability with mounting the seat.

Every review for this is on par.
Great bracket, easy setup, finish is nice.
However...
I have never seen anyone under 5'10 BUY THIS CAR!! WHY?!?!?!
I'm 5'4 I have sparco EVO QRT seat. To put it simple, I cant reach the pedals. I had to add a pillow to the back just to drive it around. I really wanted this to work. Like the 5'10 guy said in the reviews.


IF YOU ARE UNDER 5'10 OR BELOW 30 INSEAM THIS BRACKET WILL NOT WORK FOR YOU.

This bracket is "OK".

The reason most of you will be buying this bracket (like me) is that you want to sit as low as possible. Unfortunately it is NOT possible to use the lowest slots/holes in this bracket if using a Sparco Sprint seat. This may only be an issue for this seat but I want anyone else who buys this to know that! In addition, the hammering required on the trans tunnel to center the seat on the steering wheel is NOT insignificant. Expect to spend some time doing this while trying to protect your carpet (if you don't pull it out).

I had to grind off the upper slot of the brackets to recess the bracket into the seat more, to allow me to use the "second to lowest" settings. In addition, I am 5'10" and I can BARELY reach the clutch comfortably when fully depressed due to how far back I am.

- This bracket is not for short drivers
- Sparco Sprint doesn't get low enough
- When in the lower settings, the rear of the bracket extrudes into the seat hip holes for the belts, which means the belts would run over this and start to wear on it. Unfortunately I also had to grind a large portion of this down so that it would not interfere.

Other than that, I'd say it does what a bracket is supposed to. $200 is pricey though for having to modify it to work anyway! This will NOT be a plug and play bracket if you have a Sparco Sprint.

Bolted in very easily, clear instructions, Sparco Sprint lined up perfectly, and sub straps can be mounted to the bracket. No complaints, it does everything I need it to and does a very good job of it.

Five stars for product quality
Fewer for disagreement between current design and installation instructions.

Flush install of the baseplate requires more space than the transmission tunnel allows. For those unfamiliar with bodywork, instructions suggesting that you should tap with a hammer are a bit misleading. If keeping the carpet, about 6" near the front mounting point needs to move, up to about an inch. It takes effort to achieve that much deflection, and you should take your time to avoid splitting the metal, or going further than necessary. Progress accelerates once you turn the convex surface to concave.
