The change to 17-inch wheels was the trigger for everything. I started to feel dissatisfied with the body, something I had never felt before. (I think the relative rigidity of the body had decreased.)
The car is vulnerable to changes in the road surface, and the body shakes around in ruts, causing it to swerve back and forth.
So we installed a floor cross bar, which made a dramatic improvement, allowing the rear movement to be smoothed out.

When that happens, you want to eliminate the uncomfortable ride, so you install lowering springs.
I had heard that Autoexe uses high-quality coil steel, and I thought that the increased number of turns would help to reduce the input from the road surface. The results were good, and the input was changed to a rounded corner.

The improvements continue. A stabilizer is installed to reduce roll speed, and a front tower bar is installed to improve the road feel transmitted to the steering wheel and the body rigidity.
The results were better than expected in every aspect. I think I'll continue to use your products in the future. I look forward to your development of new products.
