New SVT Off Road Pipes in Stock!

These are the new one piece mandrel bent off road pipes. Also pictured is the ORP/Flex combo with the v-band connection.
There has not been one single failure with the old design, and now being one piece, they are the absolute best on the market! 2.5″ 304 stainless steel construction and completely TIG welded. The o2 bungs are relocated to have optimal clearance on lowered cars and to prevent breaking sensors.

Some new updates to the product line.

The rear toe links will now include lightweight 7075 aluminum, anodized, teflon lined, rod ends. These are better quality the the ones I have been using in the past as well as the lighter weight.

These are the new version front control arms. The ball joint plate has been redesigned to replace some of the tubing and add more strength to the entire arm. This design is triangulated more than the previous versions which increases strength. They now also include the rear bushing brackets when you purchase them.

Available NOW Mazda 3 Front Control Arms!

Here is a teaser pic of the new Mazda 3 front control arms. Fully camber adjustable with a greaseable balljoint. They will include Energy Suspension polyurethane bushings as well. These are in production now!

Where are my parts?

This is a photo of a typical batch of parts that I pick up from powdercoat every 1-2 weeks.  As you can see there are a few different colors and many different items.

Now what most people dont realize is that I outsource all my products for powdercoat. I have a local shop that does very nice work. The turnaround time varies depending on how busy they are, and/or what colors they are doing. It is not an easy task to change the color in the powdercoat gun for 1 or 2 parts and then change it again to another color. It would not be very efficient or profitable either. You also cannot cure multiple colors in the oven at the same time, or else you risk contamination in the powdercoat.


With that said, depending on what is getting coated at the time, and what color you decide, it can be finished in 1 or 2 days or sometimes almost two weeks or more  if the shop is busy.  All of my parts are custom, made to order, and that takes time. I like to offer that option, because most people want something different, and not the same as everyone else.

I am also overwhelmed with orders and have been operating with a 2-3 week waiting list. That means, depending on your order, it may take 2-3 weeks before your parts will be fabricated and sent out to powdercoat. I am a one-man operation and I handle every step of the process myself. From ordering the raw materials, to cutting, machining, cleaning, welding and checking every item before it gets powdercoated. Then the items get assembled, cleaned, packed and shipped to you. I prefer to handle every step to assure every item is 100% before it leaves my hands.  When you receive your order, I hope you enjoy everything as much as I do during the fabrication process.

More Pics!

I sent out a nice little package to Canada recently, big thanks to Mitch for ordering! He was also nice enough to snap some pics of my stuff. I sent everything out in their raw metal finish so he could get them custom powdercoated.  Here is what he had to say:

“Having spent years working at the highest levels of motorsport, competing in the Grand AM series and running the 24hr at daytona with a Porsche gt3-cup…. I can say without a doubt the build quality, precision and strength of the parts designed and built by Dominic are second to none. You will be hard pressed to find parts on and for purpose built $500,000 race cars that exceed the quality of anything from Dominant Engineering.

While the finer points to the quality of construction may not mean much to everyone not familiar with any sort of fabrication, to have products of this quality available to you at such reasonable prices is truly astounding!

I have purchased multiple sets of suspension components for my cars from Dominic and will continue to do so well into the future!”
