Both Isringhausen BMW and Dinan Corp. share a passion for European cars. That’s why Isringhausen is an official seller and installer of Dinan performance parts. On a weekly basis, we help BMW owners make their Ultimate Driving Machine uniquely their own and can do the same for you. Here are two recent examples:

Example 1

Side-by-side comparison of the old and new springs.

Dinan’s design keeps the factory Electronic Damper Control shocks in place and uses threaded collars to allow the driver to change the ride height.

Side-by-side comparison of the factory and Dinan anti-roll bars.

The replacement anti-roll bar is help up to the stock one.

Dinan Anti-Roll Bars are built specifically for each BMW chassis

The owner of a BMW M5 wanted more track-ready handling, so he invested in a Dinan Coil-Over Suspension System and an Anti-Roll Bar Set.

A Dinan Adjustable Coil-Over Suspension offers many advantages including:

Reduced "dive" under braking,
Less "squat" under acceleration,
Improved handling, and
Reduced body roll.

Additionally, Dinan’s design keeps the factory Electronic Damper Control shocks in place and uses threaded collars to allow the driver to change the ride height. The end result is a sleek, lowered stance that provides improved handling along with an aggressive look.

"The end result is a sleek, lowered stance that provides improved handling along with an aggressive look."

All street cars are equipped with anti-roll bars. However, they tend to be overly soft for maximum comfort. Dinan Anti-Roll Bars, in contrast, are built specifically for each BMW chassis, and keep your car more level to improve grip while still allowing just enough body roll.

Example 2

The Dinan Stage 1 is comprised of both computer hardware and software.

The Dinan carbon fiber cold air intake and airbox.

The owner of a BMW M 235i was interested in better engine performance, so he invested in a Dinan Performance Tuner Stage 1 and a Carbon Fiber Cold Air Intake.

Dinan’s Stage 1 Performance Tuner is a plug-in tuning device that sends a modified signal to the factory electronic control unit (ECU), telling it the boost pressure is below target values. This then causes the factory ECU to raise the boost pressure, resulting in increased horsepower and torque. In this instance, the customer's car gained about 38 HP (@ 5000 rpm) and 59 lb-ft of torque (@3000 rpm).

While there are similar devices on the market, the Dinan Stage 1 Performance Tuner enhances engine performance without voiding your warranty or affecting long-term reliability of on-board diagnostic systems. Plus, it’s legal in all 50 states.

The Carbon Fiber Cold Air Intake compliments the upgraded electronics by delivering as much outside air as possible to the engine. It has lower resistance than the stock pipe and feeds into a larger-volume airbox to produce a sportier sound. This optimized design yields an additional 10HP and 15 lb-ft of torque without any additional modifications.

These are just two examples of the Dinan upgrades that Isringhausen BMW installs on a regular basis. If you are looking for increased performance, in addition to a sportier sound and look, stop by for a consultation. One of our BMW experts will provide you with options to fit most budgets.
