The Randy Forbes Z3 Subframe and Trunk Reinforcement Episode
HTML-код
- Опубликовано: 8 июл 2024
- In this episode, the Z3 gets a subframe and trunk floor reinforcement kit made by Randy Forbes installed by Clownshoe Motorsports of Dallas, Texas. I go over the reasons for installing this kit, a brief overview of the process, and the pros/cons of having it done. I also take a moment to interview Andy Pettit of Clownshoe Motorsports and ask him about the Z3 and Z3 Coupe "Clown shoe."

Good job, I mean really, you kept my interest throughout. My thanks to you and Andy for the positive commentary*.

Where can the Randy Forbes z3 reinforcement kit be bought?
Great video! I’ve been searching for an in depth informational video about this reinforcement for our cars and yours is absolute Gold!!
This video is bang on when it comes to being informative and straightforward. Thanks man
How can I get the kit? Can't find it anywhere online.
Great Video. As a guy who just bought (sight unseen) a 98 Z3 this is good info that I hope I don't have to have done. I did get the car very cheap with low mileage.
Great video. Thanks for the detail explanation.
Well done video. I like that Clownshoe Motorsports is less than 3 hours from me too when I do decide to reinforce my subframe
Nice video! Considering the RF kit for my 99 M Roady with an upcoming (2022) suspension refresh. Thanks for sharing and good luck with your roadster.
Guess I'm fortunate that my 99 2.3 roady hasn't any rust issues, had my subframe down for doing IE bushing on the sub, and the RTSB. But be that as it may, the Koni yellows and H&R drop kit got yanked for oem struts and springs. IMHO the car was a death trap in wet conditions. Once the oem springs were reinstalled, no more hydroplaning.
Also, the two-eared approach is overkill. Definitely not needed on any Z3 including the M variants. Even cars that are tracked will do just fine with the single ear approach. Randy has two Ms that he tracks. One has the two eared job, the other the single ear. And with the single ear approach you don't have to purchase a new diff cover or aftermarket mufflers in order to obtain clearance for the two-eared approach.
So, roughly $2500 if there's no damage yet, and then how much is the kit approximately? And how much would you have in the subframe polyurethane bushings? Thanks for a very informative video!
What else is needed to do the 2 ear diff cover swap?
Hello, any chance you could send a link to purchase one of these kits?
How much did he charge you for the repair , ?
Where did you buy the randy Forbes kit?
@@Kludgecast thank you my dude, looking forward to the next video
How thick is the Randy Forbes kit? 3/16 or 1/8? Thanks,
Ten gauge (10 ga) or .120"
@@MrRandyForbes where can a kit be purchased?
Let's be clear here. This is a BMW design problem and has next to nothing to do with the car's age other than repeated flexing of trunk floor and application of downward forces will bend, crack and tear affected brackets and other sheet metal. This problem emerged quickly after BMW started putting larger engines in the Z3 when the subframe bushings were quite new. Since the Texas shop chose to lie about this (unbelievably saying that it was not a design flaw but an age issue), I'd take my business elsewhere.
Does that problem happen to z3 1.9L engine as well?
@THEWILECOYOTE ty... i have decided not to get one but if carefully buying then it is a good buy... thanks again !
