Hands down the best automotive parts customer service. Wasn't paying attention and ordered the wrong ECU for my vehicle and was able to get the proper one ordered with a simple phone call that took 2 minutes. Was informed that it would be a few weeks out but was able to get it in about a week and half. Will definitely be ordering a dash and kit when the time comes.
very well made, fit without any modifications to any of the related components. Well worth every dime!!
The only thing that could make it any better , would be to include some clips and screws for the two top mounting tabs for installation. factory screws worked for the two lower mounting tabs, but I had to source some speed clips and appropriate length screws to complete the installation. As you can see, the aftermarket gauges fit beautifully into the panel, and should be a great upgrade from the factory set up for the 5.3 LS conversion I'm doing on my 1988 Toyota 4-Runner.
Thank you for such a great product, and for the really fast shipping!!!
I'll be sharing these results on some Facebook groups that are following my build. I'm sure there are going to be some follower interested in your products.
Fit really well. This was the only UC 10 mount that I could find for my 89 CRX SI. The UC 10 is a little large and cuts off the bottom of the screen but not bad.
To find a company that produces parts for my generation civic was awesome. To have it be as high quality as it is, icing on the cake. Couldn’t be happier!
I purchased an E30 instrument cluster mount from Mako motorsport for the uC-10 digital dash. When I received the item initially the quality of the product surprised me. I didn't expect it to look so good. The test fit in the dash was perfect and when the digital instrument cluster from Haltech was installed, it was breathtaking. Well done. Mako motorsport.
Finally, a mounting solution that positions the screen exactly where it needs to be. The recessed design keeps the display at a perfect viewing angle through the steering wheel and doesn't sit too high. Installation was straightforward and the build quality is solid. Perfect for anyone running a Nexus or Elite setup who wants a seamless install.
This is my second dash I've bought from mako, just upgraded to a Haltech so I had to get another! They aren't cheap but the quality and fit is second to none, absolutely love it
Sadly Haltech was short inventory during my order time - however very happy with the product between my uc10 dash and the seamless integration with the Mako Motorsport cluster mount for it in my GC8 STi looks great! Highly recommended which led to my purchase and I'm now recommending the same to others! High quality; looking forward to my car running under its own power to truly be able to use this!
Fit in the e36 M3 dash was excellent and makes a nice mounting place for the AiM MXP. Side button (can be an issue on some other brand mounts) are easy to access.
Came out amazing, they built me exactly what I asked for in the dash. I did have to cut behind the bezel to have it all fit but nothing that matter and everything fit perfectly. This is my 5 bezel from them and I will be ordering more.
