BRG Evora Lowering Springs: Buyer Beware (British racing group)
After purchasing these lowering springs, I have found that the fitment is very poor, if not next to impossible on my 2010 lotus Evora. Before anyone asks, I have a masters degree in mechanical engineering and have been wrenching on cars since I was a kid.
To my knowledge, dimensions for all Evora model springs are the same and BRG states that they are the correct springs for my car. I sent them pictures showing the spring’s measurements and spring perch’s measurements. They state that they’ve never seen the problem. I even had a shop quote me to machine my spring perches and sent it to them. They no longer respond to emails.
The problem is that the top of the spring is slightly too large causing the installer to have to remove the rubber isolator OR to machine the top perch slightly larger to keep the isolator (which is an important part). The bottom of the spring is slightly too small so that it does not fit over the bottom perch unless you force it over with much effort, after which, the spring will bind on the perch as it moves and will wear off the coating and make noises. The solution here is to machine the perch or have new ones made.
I have written this email in hopes to make buyers aware but ultimately, in hopes that BRG will improve their product and customer support!
