I recently purchased the belt tensioner from Alta and had it installed. Had I only known over the past several thousand miles that my shock was bad, I would have changed it sooner. The shop guys brought the old one out to show me that it was completely useless. Since replacing it my mileage has increased dramatically, and performance as well. apparently the drive belt was slipping on the super charger. And power, all I can say is "Yeah, Baby". Thanks guys for making this part available.
I have purchased your stage 1 speed upgrade and the results are amazing.
Next I plan to add the header & exhaust. Also the brake upgrade.
Thank you for your research and advice.
I think it would be helpful if you also added a suspension replacement/upgrade option like your speed upgrades.
I am a pretty much amateur with all the products available, and as an owner of a 2008 convertible S will be needing to replace these components soon.
Please provide upgrade options.
I ordered the NM power module and a K&N CAI for my '16 F54 S Clubman. Both were very easy to install with the attached instructions. Shipping and service were excellent and I will continue to buy any items I need from these guys.
