You did know they were adjustable right?
We show you how to adjust them and also do a spring upgrade for ride comfort while we're at it.

Wish I saw this before I installed all my red Koni shocks. I'll wait and see how wonky the ride is :)

I do wish there were more consistancy with how they are set when shipped. And I also wish F5R would include the Koni instructions with the coilovers. Near every car I get here in the shop, the owners never knew they were/are adjustable.

Thread locker and nylon. Who knew? (I mean besides you). I know now. Thanks!

Great video as usual. One question I have though at the 5:30 minute mark you stated the rear end gets even more squirrelly with a front sway bar. I thought adding a font sway bar adds understeer to the vehicle and a rear sway bar adds oversteer to a car. I tracked 911s quite a bit and I am very used to snap over steer having the engine over the rear wheels and when I started driving my Roadster in Gelcoat I could feel the oversteer in the seat when I was pushing toward the edge of the tires with rear end wanting to meet the front end. My rebound setting are all set to soft with the ride height set per the manual and recommendations on this site. I had my car aligned by a pro and had more camber than usual in the alignment to help it "squat " in the corners. I added a front sway bar and I noticed it added understeer to my car planting the rear end more. Maybe it is an issue with set up on my suspension. I will pull it and drive some more with out it to see how it handles. I have a 3 link and no rear sway bar with power steering and maxed out caster of 8º. Just wanted your opinion. Again thanks for putting out the content as I know it is a lot of work.

Yep, a front bar will cause the front to 'push'.

IIRC the part of (LocTite) thread locker that "gasses off" is Acetone.
Use it near ABS parts and watch the fun there, too. :(

I think I said "tail happy" but squirrely works just as well. I try my best to use layman's terms as much as I can, cause God knows my mouth doesn't always do what my brain tells it to. Tail happy refers to the backend wanting to step out during braking. Add a little steering input to the braking and bad things happen. Most people are never going to push their cars to the limits. However, panic braking can cause serious butt puckering. Someone not familiar with their car, in those situations, is going to have the back end come around........... quick. Best place to learn how to counteract these situations is to participate in local autocross events with a controlled environment.

Don't make my buddy Frank talk too much---he has a daily allotment of words and when those are used up......
Here's the deal; with the factory spring rates these cars have a moderate steady state understeer. Adding a front bar or otherwise stiffening the front without a corresponding change to the rear will exacerbate that push. What happens in an aggressive driving situation is that when the driver feels that understeer has taken over and the car isn't turning they lift (or worse yet brake) which unloads the back end and brings it around. It's called "snap oversteer"---some might say tail happy or squirrely---but when it happens most say something entirely different like "oh s#it" ;)

Thanks for the explanation expounding on Franks response. Makes sense. My driving style tends to not go in too hot into corners learning my lessons with my 911. I will drop the bar and plan on doing some autocross in this rig this summer. I will push those aspects in a relatively safe environment :)
And I do really appreciate Franks videos. They are wickedly educational. I learn something new everytime he posts one up.

When it pushes and understeers, the right pedal makes it stick like a slot car. :eek::rolleyes:
