All for just $74,900.
We can't help but love the newest extensive tuning job done to the BMW Z4 by iconic tuning house Dinan and dealership Isringhausen. This car both looks and performs in a way few modded Z4s have before. The car Dinan started with was a new 2015 BMW Z4 sDrive35i. When it was stock, the sporty roadster made 300 hp and 295 pound-feet of torque. Now, the car cranks out 406 hp and puts down 430 pound-feet of torque. This is why we feel its justifiable to offer this car at $74,900.
The stock version of this same drop-top goes for an MSRP of $57,900. So how did these two tuning house make this car churn out so much power? The biggest factor here is probably the fact that Dinan installed a Stage 3 tuning kit. To be more specific, Dinan added a high capacity oil cooler to deliver power more predictably and hopefully extend the life of the engine. The companies also added a Dinan High Capacity Intercooler that's twice as big as the stock unit from BMW. Another addition is a K&N air filter so that optimal airflow can still be achieved when the boost is high. A Bilsen B12 Pro-Kit Sport Suspension Package was installed as well, allowing the car to sit more than an inch lower than a stock Z4.
An aluminum Turner Motorsports strut brace was added to increase the rigidity of the chassis even when it's whipping around hard corners. To further the aesthetic appeal of the car, Isringhausen put the car on 19-inch OZ Leggera rims with Michelin Super Sport tires. In case the lowered center of gravity and OZ wheels weren't enough to make this car look better than the rest of the pack, they also threw on glossy-finish black kidney and lower grilles made by BMW.
