Brilliant video, well presented Ash!

[@RegalAutosport]

Thank you 🥰 Glad you enjoyed!! Must be weird seeing your car in bits on KZbin, haha!

@@RegalAutosport Lol, had to clean my glasses a few times. Great experience all round, I’m sure I’ll visit again!

The M performance is a clutch plated diff, not like the Quaife. I’m not sure the Wavetrack is ‘better’ than the M performance, rather similar in the performance. The Quaife acts like an open diff under normal driving conditions. Would you recommend doing tension struts as well as LCA’s?

[@RegalAutosport]

Have you driven both too? We have plenty of dealers that swap out the M Performance for a Wavetrac, recently Tom Wrigley did the same after struggling to send their M240i sideways with the M Performance diff. You need to install both the 'tension arms' as well as the LCAs. The kit link is in the description

@@RegalAutosport I have had a Quaife myself on my E46 330 and had no problem drifting that, and a few friends of mine have M performance diff’s on their M140i’s, who also had no issue drifting. At the end of the day, It comes down to the driver. All three diff’s are going to give you the ability to have a more controlled power delivery and to be able to control the back end on the throttle. Cool, I was worried about the major change in geometry from installing LCA’s, especially how far the push the wheels forward. I’ve been told tensionstruts cancel that out when fitting LCA’s.

[@RegalAutosport]

Nice! It’ll be interesting to hear what you think once you’ve tried a Wavetrac too. Yeah, we supply the full kit so you don’t have to have any worries 🥰

[@roadreg1820]

@@RegalAutosport I will be installing the M performance diff on my 140 very soon. I am buzzing to go from an open diff to LSD. I remember how big a difference it made on my 330, and I’m expecting the same. That’s good to know! I’m in Bogor Regis, so not too far from you guys! Might in touch in a few months about that. Thanks guys! 😎

Eh?

[@scanr10]

stupid question: I know on the later model m140i's they've opened the front left lower vent for OPF cooling, is there any benefit on opening it up on the non-OPF versions?

[@RegalAutosport]

Thanks for the comment, it's not something we have taken note of. Next time one comes in, we'll take a look and see what it feeds.

[@JovanKorica1]

i think its an additional oil cooler, not an OPF-cooler...

[@markiboy100]

It's a shame you weren't offering the replacement pumpkin service when I called last month. The only option was to leave you the car for 4 days. I went to Birds and got a quaife fitted which is absolutely superb (as I'm sure the wavetrac is too)

[@RegalAutosport]

We offer this all year around... just sometimes a the appetite of the BMW community is so much it outstrips supply. We now have all the BMW applications back in-stock! Ready for ya when you wanna feel the difference between the Wavetrac and the Quaife, enjoy!

[@ArnestoGTI]

I've seen you use a lot MOTUL oils, ive heard they are good, are they indeed that good? Should i consider them for my engine oil as well? By the way once again amazing video. Thanks.

[@RegalAutosport]

We sure do! As an upgrade oil for higher output/track use, this is generally what we use. It’s actually fairly cost effective too!

What’s the point of premieres? Genuine question.

Awesome!! Hope you enjoy the video, this customer is super pleased by the upgrade 🙏

[@ARDEN440i]

Hey Regal. I've been looking at the F32 440i as of recent and I noticed that despite that it shares the same B58 engine as the M140i, it comes out of the factory with slightly less hp. Do you know the reasoning why that may be? Slightly de-tuned perhaps? Will that result in a stage 1 or stage 2 440i making less power than an equally modified M140i? Cheers.

[@RegalAutosport]

Max output is generally the same when tuned! Go with whichever car you enjoy most!

[@tavulechinois]

What alignment setting shall we choose in the computer? M4 or M140i?

[@RegalAutosport]

The front camber is fixed, we usually do a 'fast road setup' based on our own settings.

[@tavulechinois]

@@RegalAutosport Thanks. What are the LCA parts number to order?

[@Rehbraun]

Change the lower arms without PU bushes. It’s like the half power of the lower arms 🙄

[@RegalAutosport]

Still a stock M4 atm, some people don’t want the extra cost and NVH of an aftermarket bush.

[@Rehbraun]

@@RegalAutosport yes that’s true. It’s of course a cost factor in this case. But it’s like sex with a anti baby pil + a condom. It doesn’t match together. A bit crazy comparison, yes...
