They make a good bang for the buck mod. I'd use them again.

I also used Megan and Godspeed for the same reason, they've been fine for about 2 years now. Yellow PowerFlex rear subframe bushing inserts as well as rear Swaybar when i installed my coilovers. Handles so much better, much flatter around corners now.

EDIT: useful diagram below from powerflex. Looks like the ones i should change when replacing the sway bars (that make sense to change at the same time, excluding the sway bar ones as they come with the kit), are just 19 + 20 = the rear subframe front + rear bushes.

The rest i can do on my own if i feel the need to, without having to do anything complicated like lowering subframes. Right?

browsing around the forums, looks like i should look into
- rear subframe bushings - Solid delrin https://www.bimmerworld.com/Suspensi...shing-Set.html

A number of forum posts i've come across suggest that these bushes are not suitable for street, because of the additional bumps etc.. not found on a track. And therefore could deform and give me a headache.
I need to find out if these rear subframe bushings will be useable for daily road use and not cause damage....... the car will be doing anywhere up to 10000 miles annually.

- rear differential bushing (going to ignore for now)
- front control arm bushings. (VAC monoball)

furthmore, reading around, it sounds like Monoball might be my best bet due to excess wear reported on control arm poly bushes? according to a post by Watsey

if you're tracking the car, you should consider KMAC caster and camber adjustable bushings...I have their camber adjustable bushing and so far its doing the job.

Ive never used the monoballs so can't speak to them. the monoballs are a low maintenance solution so if you don't want adjustment, this is a good option for you.

Remember the rules.
Bigger front bar adds understeer, bigger rear bar adds oversteer..
Bigger rear tire adds understeer, bigger front adds understeer.

That’s why you see people upgrading only the rear bar and saying it is fine. They added more understeer with staggered wheel sizes and larger rear tires, and the bigger rear bar dials that back out and some extra to get rid of the “safety margin” of extra understeer cars have factory.
That and some people who grew up in the analog days are simply more comfortable with neutral to super mild oversteer.
