To address US demand, BC was able to raise funds in the early 2000s and launch its own BC Coilover Kit. It was a good price from the very beginning because the whole thing was made in Taiwan.
It took on more popularity after it started being sold in the US in 2004, where it made the maximum profit. Here they started by producing and selling comparatively smaller products.

D2 Racing vs. BC Racing – Head-to-Head Comparison
Here comes the real head-to-head comparison. In this portion, we’ll compare some common factors regarding their coilovers. Let’s see.
Damper Type
BC Racing BR Series is one of the most well-respected coilovers from BC, so we chose it as our baseline model. What makes it stand out and why it’s so popular among buyers is that it offers such an efficient shock at an affordable price point. The BR Series boasts an exceptional price of just under $1000 for most kits, but it contains a variety of features of coil-over shocks that cost much more.
On the contrary, the popular model D2 Racing comes with a twin tube shock design. Now, you must understand that the benefits of a modern tube shock are explained by a twin tube shock, which has an oil diaphragm.
In essence, the two are comparable in that the dual-tube shock is still powered by traditional pistons with channels that control damping during compression and rebound as the pressure of the liquid changes during compression or rebound.
The floating piston causes the primary and secondary pistons to control the operation of the system by preserving an inventory of compressed gas and by eliminating them in separate tubes. However, the dual-tube design is not particularly proficient at combining crude oil and gasoline, leading to inconsistencies and sharp changes in pressure.
Top Mounts
Both of their coilovers come with adjustable top mounts for the wheels and separate camber and caster adjustments, so both receive 5 points. In conjunction with the automobile, an adjustable saddle for the wheel permits the user to easily adjust the camber and or caster of the suspension.
Damping Adjustment
D2 Racing coilovers deliver bump and rebound adjustments separately for individual driving styles. Whilst, BC has independent adjustments for bump travel and rebound speed, giving the user many setting-up options. The BC uses external reservoirs for enhanced capacity. Tein scores 0 points, BC scores 10 points for the bump and rebound adjustments, as well as 5 points for the reservoirs.
Upgradability
They are both equipped with standard inner diameter springs, making it easy to change the spring rate when you have to, and you can get the springs cheaply, without getting them from the manufacturer. Each of them will get 10 points here.
