I got an alignment & my handling got worse than when I just installed the coil overs. He has me less than -1 degree in the front. -2.6 in the back & my caster is 8.9.
It feels twitchy, less stable & doesn't handle as well. Both front & back are less planted.

What are good number for caster, camber, front & rear etc. Anyone have a good set up.

I am running Avante Garde M310 with Hankooks Ventus 275 rear, 245 front. I will roll the fender if I have to & get adjustable toe arms if I have to but I feel caster should be maxed or at least 9.5. Feedback from people who truly understand this would be vastly appreciated. I am a retired F-16 mechanic at 38 & install was cake but numbers should be known for aggressive 19's by now. I could throw the car in any direction without any worry, loss of confidence or even a squeal. Now it feels sketchy & the *** end is even a little looser.

 

First you need to find a shop that know what they are doing. You should have more negetive camber in the front than in the rear. I run -3 in the front and -2 in the rear. You can run the rear with more negetive but on a rear wheel drive less negetive camber in the rear will help get the power down quicker on corner exit. You also didn't say what your toe was. It needs to be zero in the front and a slight negetive in the rear. If you have a postive or zero in the rear you will be all over the place. You can not ajust caster on our cars so don't worry about it. Now that you have coilovers find a shop that can do your alignment and a corner balance. If you have lowered you car you are going to have to get ajustable arms to get everything set right.

 

Here are my specs for 19x9 245/35/19 and 19x10 285/35/19 lowered on stance coilover and es bushings, with everthing else OEM suspension parts. I didnt have to roll or stretch my fenders and they fit flush with no rubbing.

 

I have friend that does alignments at Nissan and only charges me $20 to do it.
