This is what I have on my 88 DX/LS Set up.

Neuspeed springs (Green), Tokico Blue shocks, Neuspeed front and rear strut bars, Skunk2 lower tie bar. I was doing around 100 mph on the freeway and notice how the car bounces around and doesn't have a real solid feel especially when changing lanes. Do I need swaybars? I'm a little worried because when I finally get my new motor, I know I'll be driving at least 140 mph. By the way, I have Falken tires on a 15 x 6.5 Rota subzeros...

 

You probably should not drive that fast.

 

check your alignment

 

Are the green springs race or sports??

 

its probally something with the rims and tires either balancing or poor treadwear etc. i had same problem and found out my rims had a flat spot

 

yea i was gonna say rims or tires. thats the most likely culprit. your alignment could be outta whack but you would notice at lower speeds too. u never know u could have been flyin along caught some bad air off another car and it created some turbulence. but i would bet on the first 2. unless u are at indy in which case it is prob # 3

 

First, Green neuspeed are Sport springs. 2nd, I agree with not driving that fast but I was in a process of smoking a turbo beetle and a VR6 through traffic. 3rd, you're all probably right too about my alignment. After doing my swap, I haven't gotten them aligned yet, due to bad axles that I'm still contemplating/procastinating on replacing. 4th, Tires too could be the culprit, because they're the bottom of the barrel of Falken tires. Although they're fairly new, I should change em to a better brand/model in a few months. 5th, no on the flat spot...it would vibrate if that's the case but it doesnt. Thank you all for taking the time...It was fun though to see driver's face of the turbo beetle ...he couldn't believe a DX sleeper was passing him on straight aways... VR6 was keepin up though, but I lose him on weaving and speeds between 75-110...Probably a scardycat

 

Get lower profile tire cause they flex a lot. Should be stiffer.

Get poly urethane bushings and have fun putting them in

pollys are about 120 US for kit

 

I agree, you should go with new urethane bushings, but be advised your car will be [qb]ALOT[/qb] stiffer and you'll feel every little bump in the road. As for a quick fix, it sounds like either you need to check your tire pressure and if that's not the problem get your tires balanced. You should also get an allignment if you didn't when you put your new wheels on, but that won't cause the bumpy feeling, an alignment straightens the wheels so you drive in a straight line and don't drift to one side when the steering wheel is centered. And with driving fast, I've done 120 with only different springs, a 2.5" drop, stock shocks and stock 13" steelies with no problem. I do that alot keeping up with my friend's turbo 97 Civic.....oh yeah, with the stock engine too.

 

Don't they need to be pressed using a special tool or taken to a local shop? I see the bushings go for about $135 or so...Anyway, does the new extra weight on the LS have something to do with it or the fact that I snipped and hammered my crossmember to fit the JDM header. It may flex more now due to the fact...Because when I had my stock d15 motor, cornering and high speed lane changes felt more solid. (speed may not be that high though, lol)

 

Zeal B2 coilovers, spoon sports sturts/tie, sus tech sways, camber kit....and drive much much FASTER.

just a suggestion here... unless you have a real buttoned down ef chassis, driving around at 140 mph may not be the best of ideas. these cars were never really intended to go THAT fast.
