Help! Z51 suspension and car goes left on accerleration

[Kawasakisteve]

As the title states my car is fitted with adjustable suspension and it doesn't work. Any ideas or suggestions would be helpful.

Also the car goes to the left when I hit the gas no matter how gentle I am with it and when I lift off it goes right. I've just had it M.o.t tested which is a safety check here in the uk and myself and the tester couldn't find out why everything seems tight as a drum the only advisory I got us that the parking brake could be better so I'm not sure where to start.

I did get a set of strengthening plates that go along the transmission tunnel but I don't think it's chassis weakness as it does it no matter how gentle you are with the throttle.

Thanks.

Check the rear toe rod ends for play. It takes very little play to make a big change.

I've gotta get it up in the air again and have a look but it feels like the chassis is twisting

Have you installed C Beam plates?. Very likely it is deflecting since rear is moving in relation to trans

The car doesn't need C-beam plates at this point.

Check the entire suspension for worn bushings, worn front or rear tie rods, worn wheel bearings, loose suspension mountings, bent rear control arms or lateral links. Next, make sure the power train mountings, two on the engine and two on the rear axle housing are tight.

Then, have the front and rear ends aligned.

Totally agree with Hib.

Have you installed C Beam plates?.

Yes, waste of money, IMO. Same problem; no change after. Sixteen new heim joints helped quite a lot, however.

Obviously, something is moving/shifting in the suspension under load/no-load; probably the rear. I suggest finding out, as has been recommended, what is worn and replace it or every bushing, etc. back there.
