I am looking to upgrade the shocks with Ground control 375 front, 250 rear, spring rates. I am running a 94 m with 205/45/16 tires and NB sport brakes. She has a torsen rear end and r package sway bars and springs along with a front strut tower bar. I live out in the country and need the stock suspension travel but I am hoping to get rid of the snap coming out of the 55 mph 90% corners. I will more than likely upgrade the front sway bar, but my question is kyb g-2 or kyb agx? As the little road with our pot holes wears out shocks I want to stay on the cheaper side then go to full coil overs later.

AGX has way too much high speed damping and therefore ride very jittery and lose traction easily onall but the smoothest surfaces. Most people hate them passionately. The GR-2s have too little low speed damping and therefore will lack the controlled feeling you are likely looking for. Neither one will be able to handle the spring rates you are interested in using later.

Get the 99-05 Sport Bilsteins. They will be confidence inspiring and taut with stock springs without being jittery and annoying. They handle dampening spring rates up to 400/300 so well that you wonder why your car didn't come that way stock. I've run them with 550/350 and they just start to get a little busy at those rates.

Bilstein shocks

If you ever wear them out Bilstein will rebuild them for $65 each.

You will want to upgrade to NB tophats.

Thanks that tells me a lot. What would you recommend in regards rear strut tower and sway bar to help hold the rear end down on weekend back road fun. Or auto cross. But mostly I drive good weather to work or sight seeing in the hill country.

If the back is loose add more front sway bar or more front spring rate. You are likely rolling over in corners until you are firm against the rear bump stops. This then sends the rear spring rates through the roof, causing massive oversteer. Increasing the amount of travel before striking the bumpstops will delay but not stop the effect. The stock rear spring rate is only about 94lbs per inch of travel. The front is only 154-168 lbs per inch. This means the car gets onto the bumpstops easily when pushed.

Adding enough spring to keep the car off the bumpstops in the corners will actually let the springs carry the weight and still leave some travel for the irregularities in the roadway and let you control the balance of the car front to rear. But to go up in spring rate you will need better shocks to control them, like the Bilsteins discussed above.
