Exactly great mod, will be doing it when my bushings get soft.

As the forum member who did this and obviously does not want to wade into an argument has done far more performance mods to his F30 than those in this thread over the past 2-3 years of owning a F30, I take him very seriously. He has done mods and changed them if they did not give the desired results. He continues to tweak his F30 and has been very open with me about what mods worked and which mods did not. As a result, I take his information very seriously and will not be doing this mod.

perspective is always good along with experience too. I don't think any of us want to do a worthless mod, let along something that makes things worse.

That’s understandable. The other option would be either the Dinan ones or Turner ones. Both are f30 specific parts.

Fair enough. Why would you being doing this mod, though? You already have an F80.

I would think you should also check how much is left in the steering rack inner tie rods for adjustment. The control arms are pretty long.

When I saw that first video I mentally questioned the change to the axles. Costly mistake.

I also have several highly modified F30s if you read carefully

I had the same question which I called Turner for an answer on since they sell these specifically as an F30 kit, they said that the inner rods are just long enough to accomodate. From my inspection after install and seeing other people's pictures, that's true.

I had no idea, that's awesome.

I am sure Turner wants to sell parts.. ECS Tuning has a ready to go full kit for this too. What was their take on it? Good idea or not?

Highway stability and tracking improved after the upgrade. I did a 1000 mile road trip a few months after having them installed and the increased caster improves centering force which keeps it tracking more true with less input.

Take a look at the threads on 2addicts on the topic, there are tons more people there who do this mod. The F22 and F30 share the exact same suspension architecture and geometry. Here's one of many, but a search for "F80 LCA" will get a lot of hits.

Thanks, this sounds more realistic.

Im definitely pushing forward with this mod although it likely wont happen until '19 at this point.

Any N20 / N26 powered ?

Turner and ECS are co-owned.

Of course, always keep that in mind talking to anybody selling the item in question. However, I had already purchased the arms from FCP Euro before calling them and told the guy as much right off the bat, he laughed and said he didn't mind and understood that there was nobody else I could really ask. He said they had installed them on a ton of cars already and didn't have any problems reported regarding the tie rods and getting the toe set correctly. He didn't have to help me out, but he was a nice guy and I believe his answer was sincere. Several thousand miles and a few track days later, my experience corroborates.

I need to do this on my F30, does anyone know if the spacers are necessary for the F30? Or was that just needed on the F22? I'm planning on doing both Control Arms and Thrust Arms as the the F30 out of the box handles like trash and seriously needs camber up front.

[52172]

Fcp euro has a full kit as well. They have a lifetime warranty on everything they sell too. So it will be the last a arms you’ll ever buy.

A few people reported using 1mm spacers on their LCAs, but most (including myself) did not.

The tension struts/thrust arms do require spacers since the bushing is more narrow on the F80 part.

This post has the specs for those spacers, and the thread has a lot of good info.

Did you install yourself or pay someone to do it? How much did it cost (labor)?

I gave it SpeedSport Tuning in CT, they charged 1hr/side + alignment which was around 400 with tax. I had a track day a week later and wanted it ready, but I don't think I would have DIY'd it even if I hadn't. You can see the before and after alignment specs in my earlier post. My foreman told me they needed to adjust it before they even could get it on the rack correctly.

Am I reading your alignment sheet correctly? You were only able to get -1.5 degrees of camber???

I was hoping to get at least -2.0 with -2.5 or greater to be ideal.

Why would you expect at least -2.0? F80 alignment spec mid-point is -1.5deg.

Thanks.

My camber could have been a little more aggressive, but I also had my suspension raised up a good bit while they did this install. I've read that you should expect between -.8 to -1 increase with the arms. I lost about -.2 off my pre-LCA alignment to the height increase.

To get into -2 territory you'll need either camber plates or a combination of F80 LCA and the F30 -.5 correction hub.
