STAGE.II Oil Cooler + Impact Frame Package

Every breakthrough at Griffin Motorsports starts the same way — with the belief that “good enough” is never good enough. We don’t wait for something to fail before we make it stronger. We chase the weak links, we study the data, and we refine the design long before anyone realizes it can be improved (at least that’s the goal). That relentless mindset is exactly what drove us to create our Stage.II Oil Cooler package. A bigger, smarter, harder-hitting system built for the guys who refuse to settle. The next chapter drops in June 2026. Stay tuned… the future of ZL1 cooling is about to get a whole lot cooler.

PRE-ORDERS are OPEN: We finished the final hose fitting today (June 6th) and should have the final hose sets in hand in 2 weeks or less. For that reason, we are opening up pre-orders, as we only have 15 sets worth of product this batch, so it will be a first come first serve basis. I will be working on the revised installation instructions this week also.

Update from 6.6.26; Testing on our 915rwhp SHOP CAR, has been going very well! Preliminary data shows a noticeable improvement in temp reduction thanks to the larger oil cooler and increased flow evidence by the 15% pressure deduction (at the cooler) achieved by using the larger -12AN lines. During a recent set of 45min test logs in 85-90F weather, the GMS Stage.II Oil Cooler Kit was shedding 30-40F+ of heat out of the oil at various stages of the drive. As hard as we tried, it was difficult to get the oil over 215F and even better, due to the fact this kit separates the oil and coolant, our engine coolant temps averaged 170F the entire test further reinforcing the benefits of going with an AUX Oil Cooler like ours.

Additionally, we have preliminary data from 2 track only cars. The first was previously using our smaller Stage.1 oil cooler on a higher HP car, which brought peak oil temps down from 300F to 270F, but that was not enough. So after a full season he decided to upgrade to our larger Stage.II cooler and on the next session temps dropped again down to 250-260F. Thats a total reduction of 40-50F from stock.

The second car was easily seeing 290-300F on a 700rwhp ZL1 making 16psi. Over the winter he added another 150rwhp (now making 19psi) and was very worried about oil temps. Despite making nearly 850rwhp, our Stage.II Oil Cooler kept his Oil Temps under 260F the entire track day, giving him the peace of mind to stop looking at the oil temp gauge, and allowing him to focus on the track.

For this reason we are going to brand this is our “track” package and the smaller Stage.I Oil Cooler will be designated “street”. Considering that we ran our Stage.I Oil Cooler on our Shop Car for over 2 years with no issues when it was making 700-840rwhp, we are confident in it’s ability to help keep you cool, and provides all the same benefits of separating the engine coolant and oil within the OEM oil cooler.

Stay tuned for more updates as we get data from TWO MORE dedicated track cars testing this kit soon, as well as our build up of inventory which includes the addition of DYME patented quick connect hoses and fittings! The final touch that will make this not only the best looking, best performing oil cooler on the market, but will make it the easiest to install and service of time. Cheers to going faster and staying cooler!
