A Look at the Sikky Sub Frame for Your Drift Car

Posted on May 6, 2015 In Buy This Formula D Merchandise Rapper Dan Savage


As I was wandering around Long Beach something caught my eye in the Sikky pit area. On display was a highly modded S13 subframe with a massive rear that looked like something you would see in a MAC truck. I had to learn what it was all about. James Evans was there to fill me in on the details. He explained to me that this was one of Sikky’s Quick Change Rear and Subframe setups.

The whole concept behind having a quick change rear on your drift car is that all tracks are different and depending on the course layout you can find yourself in a situation where your gearing is far from ideal. The quick change rear will allow you to make changes to your gear ratio in less than five minutes. There is a limited amount of time to set the car up for each track and the quicker you can get back out on course the better. Changing an entire rear out just doesn’t make sense when there is an option like this. Now Sikky wasn’t the first to start putting these rears into drift cars but they have definitely refined it to a new level and made it into a production part. Having them ready to go on the shelf instead of a custom made to order. What separates the Sikky sub frame and rear set-up from the competitors is the technology and process they use to both develop and manufacture the product. There is a lot of time and effort in the R&D stage to locate the ideal position for the rear. Using the FARO arm they scan the underside of the car, sub frame, mounting points and then create a complete CAD drawing of the back half of each car model they develop a kit for. Then using that info they position the rear perfectly in this 3d precision environment. The end result is optimal angles and clearance of all CV joints, driveshaft’s, and axles as well as perfect placement and alignment. All of this maximizing strength and reliability of their product.


There is much more to properly setting up the rear end than just welding it in place using a tape measure or ruler. Their methods allow the guys at Sikky to get accuracy down to +/- .005 of an inch when placing the rear into the sub frame. The product is engineered and tested to withstand the most rigorous conditions. Sikky sub frame and rear set-ups will take the abuse time and time again which they have shown by running the product in their Formula Drift cars. If you’re looking to gain an edge over the competition then I am convinced the Sikky IRS Sub Frame Kit is what you need! They do offer the quick change rear complete with sub frame and axles as well as separately if you just want to buy the diff or the sub frame on its own. The kit is clearly Formula Drift legal and comes for several car applications. Read the details below for what you get and what car you can place this in.

    I can dig it

  2. rotarypower says:

    No Rx7 love considering u can pick up a FC shell for next to nothing now. However the rear subframe on a FC yea nothing quick change about that lol

  3. Crispykrem3 says:

    If I’m not mistaken Race Tech Services also makes a quick change rear subframe and sell it.

  4. prometherion says:

    And here I am still waiting for them to release their rx8 v8 swap kit

  5. Tie Fighter says:

    Race Tech Services and RAD Industries teamed up to do an s-chassis, bmw, and supra subframe thats uses a Winters Quick Change as well.


    10/10 would not buy. however they do make good stuff, cant really knock there quality after working with there mounts and what have you.

  7. John Ma says:

    Are the S13, S14 and S15 subframes the same product, or did Sikky create an S13 and an S14/S15 subframe based on original geometry of that year?

  8. haubi says:

    Seems like a great product, now when is that rx8 swapkit coming? 🙁

  9. Savage says:

    S13 subframe sand S14’s are different as they(14’s) have physically wider mounting points. But the basic idea is the same.

  10. Biddys says:

    Have you had the frs/brz version actually in a car with a winters. how far is it from the ground?

  11. Savage says:

    It was still up in the air without a subframe last time I saw it. I believe they are 3D scanning the rear end still to put it in CAD.
