Wait. We are recommending riding the bump stops on purpose now? Do we enjoy spreading heartache?

Actually that is how the oem suspension works on our cars and many other newer cars.

They use the soft spring rates to get a good ride and when you push the car you actually engage the bump stops.

The bump stops provide extra support and some have dyno'd the bumpstops to see what kind of curve they have.

The stock bump stops ramp more in the front then the rear for rate leaving the car understeering.

So if you compete in the stock classes in autox or track the car hard you end up modifying the bumpstops for the behavior you want out of the car. you can modify the length or use packers for when they engage and they have different stiffness/curves.

Its actually a really good way to tune the car if you want to stay stock springs.

It also is easy to drive at the limit because its forgiving and only gives enough spring rate when needed. I have really been comtemplating setting up the car with stock springs and good shocks using bumpstops to try something new for me.

Thanks for the regurgitation, those old memories of subjects well played out in the past are the most satisfying of all

Why run springs at all? Just add bumpstops. Think of the weight savings.

But seriously, while they play a role, keeping the car flat is not their job. If you listen to the rest of FatCat's videos, you should know that low rate springs do not imply comfort, nor do high rate springs imply discomfort. So tuning bumpstops is the last step in the process, not the first.
