It may not be the body, but the alignment. I am working on solid sub bushing, poly rears, rubber fronts. The front suspension is totaly rebuilt, including the steering box. But the car is still doing this weird entry into corners. I can go into them fine, but at a certain point in turn, she starts understeering and I have to correct. Almost as if there is compression point that flips. Still thinking about fixes. The alignment is dead on the performance specs, but it may have something to do with no enough toe. I increased the toe from 1/16 last year. I think I need to put more toe in this year.

Kev, what alignment settings are you using? Did you use stock replacement ball joints and control arms? 1st gens have such lousy geometry in stock form. Are you running a rear sway? What tire psi are you running?

oops, I have my terminology wrong, I have oversteer when car goes into the corner, it tries to turn more deeply into corner, so I have to steer to the outside of the turn to keep it in the corner.

Bill sorry about the hijack

Stock front suspension, fresh rubber bushings, (but now I remember seeing the uppers may need tightening )
mono leafs in rear (re-arched with poly bushings), no rear sway
Front sway is 1" aadco bar

alignment (from memory) around 4 pos caster, cant remember camber, 1/16 toe in, (but I added more)

tire pressures are around 35-37 on all 4 tires (21570R14)

So the back of the car is getting loose and trying to come around? Ok. No rear sway. nuts, I was gonna say pull the links out and try again lol.

no g-mod, etc.? radials, right?

Right. Getting ready to put some TA radials on and get rid of those 18 year old tires. Things might work better

Thanks for the split. I am going to go look at the front end again and check the torque. Then try some of the suggestions you posted. thx

Yeah, I was going to ask the tire type as well.

The tires that are on there now are 21570r14 Goodyear eagle GTIIs, but are 18 years old (1995)
