Happy Friday Everyone!
Here's a freebie for you all. Was challenged to create the SCCA Solo Nationals courses in less than hour this week. This ended up being the result.
Utilizing USGS data + Google Earth Data and the course layouts I managed to put together this one real quick. This will end up being a long term project to clean up and pretty up a bit for the autocrossers I know...
The long awaited next update! Thank you all for being so patient waiting for this. Matched to actual data provided from the teams (see photo above), this iteration brings accurate drivability, grip, thermals and overall a truly enjoyable racing experience.
The changelog doesn't quite do the hours put into this justice but I truly hope you all enjoy it. Feedback is welcomed as always. Not...
Hi All,
Just wanted to give a proper update. Unfortunately the NightMare R update has been delayed until next week. But I promise you it will be worth the wait! A private project (the one in the photo below) is what took priority for me ever since finishing the MR2 so I've been a little backlogged on the NMR. I could pushout what I've managed to fix thus far but that's not my style, goal...
As we approach the one month mark from the last BTM NighMare R update I wanted to provide a small update and a look into another project I've been working on for a private client.
BTM NightMare R status: I've been chugging away at the update on this. I've managed to fix the steering rack so that the wheel no longer is sweeping wildly when brakes are applied with the car stopped. I also r...

It's here and 2 days early! I wanted to give you all the weekend to play around with the newest version. Less changes this time but more focused changes:
As some of you may know these cars come with DSSV shocks (dynamic suspensions spool valve). T...

The latest release of the NMR is here! Dropped this one a little early for you guys since I was a little behind with my last post!
v0.3b's biggest update is, once again, the tire model. I reached out to a few contacts I have at "SleipniR ...
In celebration of this update we are hosting a Community Race for the upcoming real-life race at Le Mans!

2b or not 2b... that is the question! No really, it is. This update took a bit longer than I would have liked it to but, there are some pretty hefty changes that involved a lot of reengineering on my end that make the jump from 0.1 to 0.2 more stark than the average update. Overall however, the driving experience is just that much better! I hope you all thoroughly enjoy, please provide any and ...
2025-06-06 15:00:12 +0000 UTC View PostI've been hard at work on all of the 2025 updates and some QoL updates on the NMR. Main update being the tires. The Sleipnirs will remain the only publicly available tire. I toyed with the addition of the "Kotobuki" Cup tires, but between them having tremendously more grip and that series being significantly less popular, I turned my full focus on the Sleipnirs.
Shortlist of cha...
Hello All,
Just a small update on the NMR's v0.2b progression! The hope was to have something released at the one month mark of the v0.1b release but we're swimming in new data for 2025.
With the real-life counterpart to this car's racing season underway we have been working with Multimatic and a few of the racing teams to develop the data of this car a bit further.

Version 2.15 of our famous Spec P71 mod has been released. This corrects all of the issues that 0.2.8 and 0.2.9p1 introduced.

Hello All,
I am aware of some bug issues going on with the Spec P71 car on CSP version 0.2.8 and 0.2.9p1. I am currently in the process of resolving these issues. Note that the P71 is set for a yearly update so this preview breaking some stuff has unfortunately forced our hand to make the car better.
As always, the update to the car will be available for free. My apologies...
The BTM NightMare R is here!
v0.1b is the first iteration of a continually evolving project and the first of it's kind in the sim racing world (ha! take that iRacing!).
The BTM NightMare R is a production-based, purpose-built track car that was designed to compete from grassroots level motorsports all the way to its exclusive single-make racing series.
Whether you're a se...

It's officially happening, I've scheduled the release for the NightMare R! Excited to finally share this creation with the world. A full, from scratch, vehicle that is second to none in the physics department. Utilizing real-world data and the help from various racing teams as feedback, we've created the most accurate to life depiction of the NMR!
The release will be available to all of ...
It's finally here – the most aerodynamically dubious, structurally questionable, and nutritionally irresponsible car I've ever built! Introducing the BTM Decheeto, a collaboration between BTM SimSport and Nukedrop, dropping just in time for April Fools' Day!
This page is for t...
Been meaning to make this happen sooner rather than later, but, being that I am a 1-man Modding Team it took me longer to set up. But our website is officially up and running. Our public releases will all end up here eventually after they have been tried and tested here on Patreon. Hope you guys enjoy the site and a little bit more lore about how BTM SimSport came to be!

NightMare R progress continues! We've finished off all the liveries we'll be including in the patreon beta release. There will be more with the public release later in the year. Driver Animations have now been handled, so that just leaves four things left before you all get to try this thing out!
Seatbelt adjustments (once driver is placed)
Interior UV Mapping
LODs
User Manual
I've been working hard to crank out liveries for the NightMare R since the last update I shared. The goal is to give you guys as many liveries as I can to fill out a field of these cars for your enjoyment against the AI. Some of the liveries are loosely based on what you might see on a real car.
I have just a few more liveries to do, while I work on that here is the list of what remains...
We've opened our discord up to all patreon supporters. Our paid supporters who have access to the upcoming NightMare R release have special channels to communicate any and all requests and bugs. We hope you'll join and make our community fun!

Hello to all of my subscribers! I am in the process of finalizing the first iteration of the beta Nightmare R for you all to drive. Expect it sometime this month! I have been hard at work developing the car into the most functional state that I can so that you all may enjoy the fruits of my labor!
With that said, I am also working on livery development and in doing so, need names and car...
Ever since the release of the Drift P71 I've had a massive increase in followers here. Thank you to each and every one of you for joining this journey.
In 2025 BTM SimSport officially becomes a LLC and with that many of my works will start becoming available here to you first, my patreon supporters.
I had hoped to have a number of our projects ready for release by Christmas, but, ...

Happy Thanksgiving to our followers! We've been away for a bit but we've got some exciting things releasing soon! One of which is our Spec P71 drift mod! 
We know a lot of you are anxiously in wait for Project SleipniR to make its debut. But we have a few other projects we've also been slowly chipping away at that we hope to release in Q4 2024!
Project SleipniR is reaching its final stages of 3d modeling / Texturing / AC Implementation. Our focus remains on providing the absolute best physics model available for sim racers to utilize while...
Tons of progress continues on the development of our next project "SleipniR". We don't officially have a name for the final car yet but that certainly hasn't halted our progress of development.
We've managed to get the physics to about 90% worked out at this point, utilizing a CAD suspension model of the real deal car and converting it into cosmic (cPhys) data. As well as have tons of mo...
Progress continues on our latest project for Assetto Corsa!
The SleipniR is a single make racecar tailored for enthusiasts who want a race-ready experience straight from the factory, making it suitable for designated single vehicle racing events as well as a variety of others.
We have completed the exterior 3d model and are now working on both the interior as well as all of the p...
We're hard at work on a variety of public and private projects for Assetto Corsa at this time. Above is a small teaser of one of our personal favorites that we're putting together with some of the most accurate physics available for Assetto. Stay tuned, this is going to get good and members here will get to drive this before anyone else!

We all remember what happened in late 2019... COVID was a weird time for a lot of people, myself included, sim racing out of a literal closet I called my Harry Potter Closet. This was my first attempted mod after seeing the Nurburgring make a humorous post on their track with this exact arrangement of pasta and TP on the racing line.
Being that it was my first ever Assetto Corsa mod afte...
