Integra Type R Race Suspension Analysis
To provide a clear path forward of improving the handing dynamics of the Honda Integra Type R for racing purposes, we needed to have a thorough understanding of the car and it’s suspension.
We started off by undertaking accurate measurements of the wheel base, track widths, suspension arm lengths, roll bar diameters and lever arm lengths, spring rates and suspension travel.
The next process was to calculate the roll centres and vertical centre of gravity through the chassis, and from this we were able to derive a theoretical base ride height from which we could develop further on the track. Following on from this we calculated an ideal spring and damper rate which TEIN were able to provide us with to special order.

Following on from our theoretical suspension calculations, we took the car to Brands Hatch circuit for testing and fine tuning the of the geometry.
We used the Race Logic V Box for data logging/capture so that we could accurately analyse the results. The data from the V Box showed that the car was still showing strong lap times even though the drivers were still getting to grips with the significant and fundamental changes that we had made.
The car was pulling more G’s than we had expected through certain corners which led to uneven tyre temperatures, so we implemented a geometry correction to compensate for this.
With some subtle tweaking of the ant roll bar lever lengths and damper rates to suit the pilots style of driving, the car was now ready to go racing!
The revised suspension has resulted in the car being 2 seconds per lap quicker over it’s previous best times, which we consider to be a resounding success.
