G-Body TBM Modular Bore Billet Master Cylinder Conversion Kit (Choose Bore Size)

Our Manual Brake Master cylinder kit utilizes a billet firewall mounting plate CNC'd from 6061 Aluminum. This plate is designed to utilize our TBM Modular Billet Tandem Master Cylinder. This requires you to drill your brake pedal for the master cylinder pushrod Kit. Includes all hardware necessary.

Years of development went into this all new TBM Billet Modular Master Cylinder which answers the needs of racers and hot rodders alike. For years our brakes have rapidly developed to create world class braking systems. However, the control system of a car's braking system is the master cylinder. While most brake master cylinders are cast spinoffs of old technology that lack options in internal and physical outside sizing, have leaking issues, and reliability issues. The TBM brake master is a ground up engineered design to remedy those questions and offer new solutions for builders.

Bosch spark plug are okay... for now.
I'm ususally a Denso Iridium Long-Life or NGK Laser Iridium kind of guy for my Acura or Honda spark plugs. I purchased these on short noticed when I got hit with CEL, grabbed my OBD2 scanner read misfire in all 6 cylinder in my J35a8 (Acura TL Type-S) when I arrived home late that night; I know right, of all places thank goodness. Anyways, I further started to diagnose the car from the least expense before assume the most expensive parts; the spark plugs upon inspection showed they reach it service life. Grabbed my phone in hopes for an overnight prime shipping and encounter these Bosch spark plugs. I installed them the next morning before going to work and all 6 cylinders misfire went away. Sidebar spark plug gap were within factory spec and are somewhat similar to OE. Its been a few week so far still good 👍. For the price it wasn't expensive but I had to order two 4 pack cause the individual spark plug took a few days extra to ship. Gas mileage slightly improve not by a lot, but I'll take it since gas price have gone up. Make sure to properly torque it with either 1/4 or 3/8 torque wrench when I last check they slightly backed out. Since I torque it down to factory recommendation it has stay put since. Will update again in the near future...

Reliable oil for BMW owners
I drive a BMW, and this is the oil I always keep with me in the car. I even have a special holder made for this exact bottle, because it fits perfectly and I trust it that much. The oil quality is excellent, and since it’s fully synthetic, it performs well even during long drives and temperature changes. In terms of functionality, the engine runs smoothly and quietly after each change. Longevity is also great. I notice that the oil keeps its properties for the full interval, so I don’t have to top it up too often. There’s also no oil leakage from the bottle, which is important when you store it in the trunk. For a branded BMW product, I think the value for money is good, especially if you service your car yourself or like to have backup oil on hand. Overall, a dependable synthetic oil for anyone who wants to use what the car was designed for.
