mild handling improvements

So what is the best bang for the buck to improve the handling on the GN? Not looking to race or autocross, just want the car to handle a little LESS like something that is 35 years old.

I tried doing a search on Hotchkis to see what of people thought of their front control arms and springs, but most of what comes up is people SELLING the stuff, so it must have not produced the desired results.

Hoping to spend 500 to 700 bucks.
Thanks

I'd go to kirbanperformance.com and get new springs and Bilstein shocks all around along with a body bushing kit and all the braces he sells.. makes a big difference

Tires, shocks, springs, braces.

Might research 1"-1.5" lowering springs. Think Eibach is available through Summit.

You're not going to get it done for $700, but you can do it for under $1000

Since you're not racing, don't overthink it. Get it back to where it should be and make a few strategic improvements, and you can get almost all of it from AutoZone or O'Reilly:
1) Body bushing kit - $~190
2) Springs and shocks, Moog 5660 front and CC651 Rear springs, with the Bilstein shocks, ~$400-$450
3) Front poly Control arm bushings: $90
4) Rear rubber control arm bushings: $50
5) Tall upper ball joints, $80 - AFCO 20032-2LF Low Friction Upper Ball Joint, Extended Length
6) A good alignment, $70-100

That's going to make it ride and handle like a modern car for a shade under a grand. New steering components could add $150 or so (tie rods, idler, etc).

If the car's not rusty and the body bolts come out, and you get a ball joint press and the tool for pressing the old bushings out of the rear end, you can do all of this over a weekend with a lift. Without a lift, the front springs can be a bear. Autozone also sells fully assembled front control arms with new bushings and ball joints already installed. They'd be a HUGE time saver if you don't want to mess with the poly.

Going from 15 up to 17 or 18 inch rims is a huge improvement. But looks and cost to consider. Hard to compare but I think this is the biggest factor to consider but I realize it's big bucks. Blown out shocks and worn parts will make it wallow big time too.

Wheel size and backspace still apply when going to 17?
Front 7 inches and 4 backspace
Rear 8 inches and 4.5 backspace

I would consider what deezdad said to be the absolute minimum. Definitely biggest bang for the buck.
Next step would be Turbo6inKY's list. I know that he was trying to keep it under $1000 but I would highly recommend that if you ever plan to hit the gas hard, especially not in a 100% straight line to get some beefy rear lower control arms too. My Global West ones pretty much eliminated my wheel hop.

Kirban no longer sells springs. Your best bet is Moog springs.
I am actually on the same boat as you. Already ordered Bilstein and now deciding on the shocks..
Planning on using 5660 on the front and 5409 at the back for a slight lowering with stiffer springs.
Changed all body mounts (prothane) and both upper control arms (stock bushings for now)
Poly sway bushings and end links.
Next, wheels and tires...still undecided on keeping the 15 or going to 17...

There are no good tires left in 15" diameter, aside from drag radials and racing slicks for Miatas.

I'm in the process of replacing the upper and lower A-frame bushings, ball joints, Moog stock springs, and outer tie rod since the outer tie rod threads, and nut were damaged, as I really checked the other suspension parts to which all were good.
The best price I have checked was RockAuto site:
Compared to many suspension sites RockAuto saved me a lot of money

Last year I put the ultra grip Cooper in 225's and they were very good
Not sure you can still get the cooper unless you fine a shop that can find the odd stuff
Now I'm on 17" front 7" rim 245/45/17 and 8" rim 275/40/17 in the back they just fit
Rims are US Mag Rambler 110 all chrome no spacers

It's my Granny's car!
IROC Z front sway bar. Replace control arm bushings frt/rear with firmer bushings. Good shocks. Bigger rear bar I have old ATR one. Summit has a larger one for decent $. Replace body bushings.

For me, sway bars made the biggest improvement in handling. I have a Detroit Speed rear sway bar out back and the 1LE in front. If you want to improve ride then address shocks, I used KYB in both cars until last year when I switched to Viking double adjustable and its night and day.
 
I just did the bilstien shocks. That upgrade alone made all the difference.

FYI...don't buy from Kirban. You can find them on Amazon for about $180 cheaper.
