Rush orders:

I understand the waiting process of 2.5-5 weeks can seem a bit much, especially if this is you're Daily Driver or race/show car that you plan on attending events with. I try to preach that I am a one-man operation and do a variety of work that always has me busy & schedules don't always go as planned so that window of time allows for some room for me to work with.  I try my best to get these done ASAP and back out to you guys but with every job small or big the process is the process & I refuse to rush and cut corners to affect the overall end product or possibly cause scrap.  

I am going to add an option for a rush order -  5 day-10 day turnaround ( From the time your housing arrives ).  This will come with an additional cost, You will have your housing shipped back within that 10 day window Guaranteed

Please read: 

If you send your housing to us and we are still within the 2.5-5 week window above, please do not email asking every day for an update. Your order will ship when completed and you will receive a tracking number at that time. Please be patient as every insert is machined specifically to size for each housing for precise fitment as well as each insert being made to order. These are not mass-produced and require their own time to process each order. 

Thank you!
