Jounce bumpers (bump stops) and lowering springs - the real dirt!

KCE explanation of your lowering springs and the impact they have on your suspension, specifically related to your "bump stops".
I missed the opportunity to to comment on the stock spring vs. lowering spring w/r to the travel difference...in the video, the 3" is after the lowering spring, 2" would have been stock springs so you wouldn't be at the jounce at static ride height but you are likely close to it/nearly touching at stock height! The B8s are slightly shorter dampers vs. stock for the purpose of ensuring the slightly shorter lowering springs are retained and not loose at full droop; you can also run B6 or other stock-length dampers as long as the spring is not loose which will often be the case; B6 and 8 are identical damplers otherwise. One difference however with going with a stock-lenght damper is droop/extenstion will be disproportionately longer than bump so here, stock dampers may give ~4" of droop vs. only 1" of bump and with the B8, you reign that in a bit to 3" of droop to keep things somewhat balanced. Hope that is helpful.
A note - I want to make sure folks understand that you can ride low and not have a terrible ride BUT you will need coilovers AND coilovers that are intended for that use...these typically have shortened bodies that are adjustable. You will choose very high rate linear springs and the jounces are typically very short. Full-bodied coilovers like a Bilstein or KW are not intended for being really low and have a pre-determined design limit to lowering that they will include in the instructions. If you slam your car on Bilstein B14s for example, it will ride terrible/bouncy b/c of exactly what I show in my video and work just like the lowering springs...the lower you go the more of the available suspension travel you are using to lower the ride height and you will be into the jounces. The difference with a B14 and my setup is you do have some up/down adjustment of your ride height for fine-tuning via the spring perch (preloader)....the higher you set the these, the more bump travel you will have/the less extension travel and these flip/flop when you reduce preload/set the ride height lower. Hope that clears that up!

Nice video, good explanation Adam!

Now I know why my suspension sucked with lowering springs on stock dampers. Thank you fine Sir.

Awesome explanation. I'm still considering if I want to lower my R. Right now it would be mostly for looks as I haven't made time to look into tracking it. My aging bones don't want that harsh ride that I didn't mind when I was a lot younger. Looking forward to more of your videos. Cheers.
