420i gets an 'ass-lift'

Stuart@BMRAutowerkes · 04-29-2015, 02:23 AM

One of our customers picked up a new 420i but wasn't really feeling the rear-end styling. We would have to agree, the front and side profile of the F32 is absolutely stunning, but the rear end in 420i/428i configuration leaves a bit to be desired.
So we set about to improve this and our shopping list included:

- M Performance diffuser from the 435i
- Supersprint dual outlet exhaust
- Blacked out reflectors

We also added a JB4 for good measure and wow this really wakes the 420i up. After doing plenty of N20 JB4s in 328i/428i configuration with excellent feedback, this was the first 20i motor we did, shame we didn't get a chance to dyno it, but the butt dyno says it pulls noticeably harder

Onto the pics!

Only one stock pic as we all know what they look like

Looks awesome, would leave the reflectors though. Without those, there's nothing reflective on the back of the car (the clusters have nothing on them) - surely that increases the chance of an accident?

Hi Stuart.

How much was it (roughly) for the diffuser and exhaust? Was interested in doing my F31.

That looks great.

Do you something similar for f30 328i? specifically the single to dual exhaust setup...price?

PMs sent, cheers

Looks cool.
I agree, the Gran coupe not looks good as coupe version.

Could PM me how much will cost for that?? I want it for my new 428i

KKK168 · 10-29-2015, 10:53 PM

Any one know any shop in Brisbane can do this 'ass-lift' in one stop!

Without shop around and provide for own exhaust, diffuser and paint job etc..

Not sure those parts from ebay will fix my car or not. I just want drop my car in and then get the job done.

Yup. Cool. Thanks

Damn that thing looks fukn amazing.

Reading someone's comment about the reflectors... That's actually a really good point. I'd still black it out too though lol.

dubdemand · 11-03-2015, 03:55 PM

Looks so much better after all your hard work! I'd also leave the reflectors red though...

Do you have an image of the 420i Coupe, I have the Gran Coupe and it looks pretty amazing, trying to find more Beemers with my model on here, but as I am new don't know where to.
