HPA adjustable endlink kit

Some people often feel their car tend to roll around a bit more after it has been lowered, I may have the answer here...

One important component often not paid attention to is the anti roll bar endlink. After lowering your car either on springs or coilovers, it is recommended to get your anti roll bar back to its ideal geometry. if you don't have the AST 4100 single adjustable coilovers with adjustable anti roll bar endlink brackets on the front struts, the only other way to do it is with adjustable endlinks. With the anti roll bar in its ideal geometry it will work properly and gives you the correct roll stiffness as designed.

One of my favorite things about the 4100's.

Cant wait to get my parts on my 135. The car is already so much more fun to drive then my 335 stock!

It all adds up when you are doing various things. Those alone will do nothing, but combined with light weight seats, rear seat delete, lighter battery, lighter wheels, hood, exhaust and the brakes will all add up to significant weight savings.

The latest addition is a 2mm larger rear anti roll bar to help the rear change direction just a tiny bit quicker since I already have as high of a spring rate as I would like to see on a street/track car.

Does this mean the project is still alive? I thought it was to be sold for a 1M? If not, I'd love more updates and pics!

The project will continue until the day I take deliver of the 1-series M Coupe and may continue if I can justify keeping both cars, otherwise all the upgraded parts on the 135i will be sold to return the car to stock.

Yup Harold is running the 18" Silver Breytons. I forgot the exact tire setup he told me that he was running but he also has spacers as well I believe.

245's PS2's all the way around for street and 255's Yokohama AD08's for track since Breyton does not make a wider rear wheel.

Both of the above may be for sale soon!

Those wheels wouldn't last a day around Northern VA with the potholes.

Yep, I am interested in those. Going to use Advans for DD I'll get back to you later today regarding the custom spring perch.
