Is it worth paying more than 1200 euros for a sports suspension or is it better to spend less than half and settle for the standard one? In this episode we will discover, with the help of Pablo David González and his BMW Z3, the answer to this question that you have probably asked yourself at some point. We have bought springs and shock absorbers with characteristics equivalent to the standard ones (Sachs/ Kayaba) and a sports suspension kit (Bilstein B12/ Eibach Prokit). With each configuration we have done three circuit tests - evasive manoeuvre, slalom and fast lap - and we have analysed the differences. In this video we will also explain what are the secrets of the BMW Z3 suspension, those details that make this vehicle behave somewhat delicately at the limit. And there is more, because we will tell you what the homologation process of a sports suspension consists of, the expenses it generates and whether all that effort is then rewarded with a better driving feel. As you will see at the end of the video, the tyres are a factor that prevent you from extracting the full potential of the sports suspension. If any tire manufacturer wants to get involved in the project and participate in a video to see how much the performance of this car improves with normal and sports tires, please write to me at [email protected]. The BMW Z3 Roadster unit is a 2.0 version from 2000. It has a six-cylinder gasoline engine, 2.0 liters of displacement and 150 HP (M52TU). The gearbox is a five-speed manual and the drive is on the rear wheels. It has ABS and traction control, but no stability control (ESP). 00:00 Intro 00:34 Presentation of the BMW Z3 2.0i Roadster 01:50 What suspensions are we going to test? 02:28 Bilstein B12 03:24 Fast lap around the circuit 04:54 Slalom 06:14 Moose test with standard suspension 10:30 The BMW Z3 suspension, technical explanation 19:10 Moose test with sports suspension 21:18 Physics: lateral load transfer and its influence 28:48 Maximum moose speed with sports suspension 29:30 Driving impressions on the road 31:30 Cost and homologation 34:40 Conclusions and future projects 35:54 Bonus sequence.
