MK7 "Random / "Stupid" Questions Thread"

First set of coilovers installed. Started on full soft all the way around. Had some pretty bad oversteer turning left while moderately accelerating from a stop.
That means I need to stiffen up the rears, right? What is the best procedure as far as dialing in the right amount of stiffness?

Larger Rotors on non PP car.
Can you simply swap out OEM rotors for larger rotors on a non PP GTI (early 2015) for a larger set - leaving original calipers in place?

 

[Strange Mud]

doubtful....you prob need to put on different caliper mounts to move them out to clear larger rotors.

 

[Raguvian]

You would at a minimum need the caliper carriers, and I may be wrong but I don't think you can use the PP caliper carriers with the non PP calipers.

Do you mean understeer?

What phone? In contacts in the settings there should be a choice for first or last name first. The voice prompts would be in the general settings.

In Voice prompt settings I see nothing to turn off the confirmation stuff, just beeps and explanations.

Back end started swinging around and I had to steer into it a little to catch traction again.

Stiffening the rear while it’s already over steering will make the problem worse. Either stiffen the front or soften the rear.

Thank you. Rear is as soft as it goes right now so I'll add some clicks to the front and go from there

Aftermarket rear sway bars can also exacerbate oversteer since coilovers are already much stiffer than stock suspension. If you have an adjustable rear sway bar you might want to put it at a looser setting. Adding camber in the rear would also help.

Nope....the 312mm to 340mm swap involves different calipers & carriers..the 312mm (GTI) has a 57mm piston..the 340mm (PP) has a 60mm piston.....

even on the my 288mm to 312mm swap which uses the same caliper, I required different carriers to move the caliper further away from the hub to give more room for the larger diameter discs..

I didn't think that coil overs would do that with the natural tendency of the GTI to understeer. Did you add a RSB also?

I ran 235s on a 7.5 wide wheel and it felt good.

Would that work with an 18" x 7.5" wheel? I would like to run 235/40/18 tires ( stock is 225/40 ) but the minimum recommended width is 8".

I've honestly never jacked up my own car but want to because check something under my car without asking someone to help. In the rear can I use a floor jack to jack the car up from the pitch weld? Or is there another spot..? I am trying to raise the car so I can try to spray some lubricant into my LCA bushings.

Yes, at the pinch weld. VW even put an arrow on the underside of the rocker to show you where.
