Swapping GT350 Hubs into My E90 - Any Advice?

Performance & Modifications
1

I’ve been considering doing a performance upgrade on my BMW E90, and I’m particularly interested in the possibility of swapping in some hubs from a Ford GT350. I’ve heard that the GT350 hubs can enhance braking and handle better, but I have a few questions before I dive in.

Here’s What I’m Looking At:

  • Compatibility: Are the GT350 hubs a direct fit for the E90, or will there be modifications needed?
  • Brake Calipers: Will I also need to change brake calipers to accommodate the GT350 hubs?
  • Wheel Size: What wheel sizes can I run with these hubs?
  • Performance Improvement: I’m mainly focused on performance. Will I actually see a difference in handling and brake performance?

What I’ve Found So Far:

  • I’ve seen some forums discussing the potential for upgrades using parts from other vehicles, but most threads focus on older BMW models or other makes entirely.
  • Some users mentioned needing custom spacers or other adaptors, but the details are a bit vague.

Other Considerations:

  • If you’ve done this conversion or something similar, could you share your experiences?
  • What pitfalls should I avoid when making modifications using components from different manufacturers?

I appreciate any advice or experiences you can share. I’m excited about the potential for improvement but want to make sure I’m on the right path before making any moves!

Swapping GT350 hubs into an E90 can be a great upgrade for handling. You’ll need to check the hub dimensions and possibly modify the control arms for proper fitment.

Thanks for the heads-up! Any specific dimensions I should be wary of?

4

The GT350 hubs are slightly wider than stock E90 hubs, so you’ll have to adjust the wheel offsets, too.

5

Good to know. Are there any aftermarket adapters available for this?

6

You might not find specific adapters, but some fab shops can custom-make them for the swap! Just make sure to get proper alignment afterwards.

7

That’s a solid idea! What about brake line compatibility?

You’ll likely need new brake lines since the GT350 setup can differ in length and fitting type. It’s a small but essential detail!

9

What about the weight distribution? Are there any impacts to consider?

10

Weight distribution may slightly change, but it’s typically negligible for street setups. Just keep an eye on how it feels during spirited driving!

11

Totally! A bit of weight could improve handling characteristics. It’s all about setting it up right.

12

I just hope no one makes this swap and regrets it halfway through! Haha!

13

Exactly! It can get tricky. Anyone got a checklist of modifications needed?

14

Definitely need to check suspension geometry! Also, you may need to adjust the wheel wells if it’s too tight.

That’s useful, thanks! How different will the handling feel compared to the stock setup?

16

Most report a much sharper response with GT350 hubs! Just make sure your alignment is spot on.

17

Can’t wait to experience that! Anyone else done this swap themselves?

18

Upgrading to GT350 hubs can really enhance your E90’s performance, especially in terms of handling and braking. The wider stance generally leads to better cornering stability, which is a significant plus for spirited driving.

19

Absolutely! I’ve seen improvements in my friend’s E90 after making a similar swap. The GT350 hubs do provide a more rigid setup, which is key during aggressive driving.

I agree with both of you! The GT350 hubs also might enhance braking performance. Bigger braking components mean more stopping power. Have you thought about pairing them with upgraded brake pads?
