Turner Monoball Tension Arms, 900 miles review 340I

I wanted to try these because I wanted better feed back from the steering, which has done it's job!

Installation - very straight forward, newtis has detailed installation instructions. I had to use the OEM bolt because the bolt that was provided is too short.

User experience
The good
- better steering feel
- easy install with great benefits
- price is reasonable

The bad
- although Turner advertises "with no added NVH noise" it in fact adds NVH noise, going over road imperfections causes the slight "thud" sound that sounds like a ball joint is going bad. It's ok driving on the freeway but jeeez on public rounds it erks me.

If you don't mind the the added noise this upgrade is well worth it.

11/15/19 Ride quality review 900 miles - the “thud” sounds is not as loud and occur less frequently, maybe they needed time to set? But it’s more easier to live with now.

I got the whole arm with the bushings. I haven't gotten an alignment yet, waiting for the coilovers springs to set to make final adjustments before getting an alignment

Your caster will change after installing these monoballs. If you look at the OE bushing the bolt hole isn't in the dead center of the bushing, it's offset towards the "car side" of the bushing. The monoballs place the hole in the center of the assembly, so it will increase your caster. My guess is that will also increase your toe in.
