Just installed hardrace roll center balljoints and reverse tie rod ends then had it aligned with following specs. The car feels a bit twitchy on the straights. I know I want more camber up front, but need to add another crash bolt or purchase my coilovers with a camber plate.

That being said is it potentially the toe out up front? It's so minimal I didn't think it would cause the twitchiness. I might get used to it and will know more after I track it this upcoming weekend. Any pointers would be appreciated.

If I should post this in the road race section please let me know.



Front R Caster: 1.7
Front L Caster: 1.8

Front R Camber: -1.5
Front L Camber: -1.5

Front Toe: 1/20 out
Rear Toe: Neutral

Rear R Camber: -1.2
Rear L Camber: -1.2

 

honestly, you should get a tire pyrometer and check your tire temps to see what you really need when youre on the track. otherwise just run what you brung and have fun. your alignment isnt going to affect your times until youre really pushing.

the roll center adjusters and flipped tie rods are definitely affecting things. but im unfamiliar to what exactly changes in feel since i've not used them.

also your EP3 isnt the same as double wishbone hondas which behave differently anyway.

 

Also those ep and dc5 chassis have sloppy steering bushings in the rack.

We're you trying to chase that problem and why you added both the roll center and tie rods?

Are even the parts you added installed tight and correctly? Check for play?

 

Thanks for the replies! Yes installed everything myself, double checked that everything was pressed and torqued appropriately. The roll center adjusters were installed and c-clip fitted, so I know they were pressed in fully. Wasn't trying to chase a problem, but according to a number of sources the geometry of the EP3 is thrown off significantly when you start lowering the car, so was trying to make sure I set it up right from the start. I'll look into a pyrometer. I've been doing a little more research and it sounds like the reversed tie rod ends do tend to increase steering sensitivity, so that might be it. I'll track it this weekend and report back.
