FS Performance V1 Nismo splitter/undertray

street2soul · 01-06-2021, 08:17 PM

Nonetheless, still good to see that someone is working on the V1 nismo diffuser and front splitter. Most aero or cosmetic parts I have seen were for V2 nismo or sport bumpers so i'm stoked.

I'm going to fabricate a V1 nismo specific splitter from 3/8" or 1/2" birch plywood to integrate with the Zspeed undertray and battleaero splitter bracket I have. The goal is to make it relatively easy to remove for serviceability and get rid of the black lip plastic. This will be an interesting project to make my car competitive towards Nasa TT3. Hope to post of my progress soon.

It will also be very interesting to see this one since it does not use the zspeed. hope I see some more photos of how it's mounting and where the mounting points are.

Edit: Also, it is very rare to do wind tunnel testing or wind testing as it's expensive. Splitters are usually designed with few key principles in mind, but generally can be very effective without doing wind testing. Drivers would generally test drive on track to find a balance of under/oversteer at speed and try to create the balance of wing AOA/rake. sometimes adjustment of front splitter is not possible, but as long as its not pointing upwards to create lift they usually work fine

You're right, everything is made for the V2 nismo or the base/sport. Post up some progress pics of the one you'll be fabrcating.

I may be the guinea pig and order FS splitter. The owner is going to verify that the splitter is sitting level before I purchase it though. If I purchase it, I'll see how it's mounted and see if it needs additional bracing. Also, I have an idea of different bolts to use to address the concern that we have with them sticking out too much. I have some bigger washers so the bolt head would be countersunk more than whats shown in the pic.

awesome! i'd love to see it if you do purchase it. seems like this company is open to ideas to make it better so that is a very good sign. could be a very nice off the shelf solution.

There's a real good chance I'll be purchasing. My car goes on the dyno tomorrow, I just want to make sure my tune goes smoothly first. They are definitely open to ideas. When he get's ready to do the diffuser, he would like our input and concerns.
