What problem is it supposed to be solving? Is there a problem with the rubber on this mounts walking around?

^I don't believe there is any rubber gourmets in between the chassis and the subframes. To my knowledge the subframes just bolt right up to the frame.
I think this product serves as like dowels to limit any movement the frame and sub frame can have. |
If you've ever taken the front subframe off the car you'll notice that the holes on the subframe for the bolts are much wider than the bolt itself so the position of the subframe can be slightly adjusted. Because of this the subframe can have some play under a lot of lateral load. The spoon sleeves close up this small gap so the subframe fits snug around the bolts to reduce play. It is a very common alignment practice they teach in alignment school to loosen the subframe and move it around to shift alignment ranges.

if it's a dedicated race car, i can see where these would come into play. but for the vast majority of us, i think it does little to nothing.
i'm happy to see parts developed for our cars, though...it really gives us a lot of options and that's always good! :thumbup: |
I run my car hard and bounce it off of curbs all the time and I have not notice any significant change in the alignment settings that would suggest that the subframe has any play in it. The alignment is not drastically effected by lowering the sub frame either (or at least that is my experince).
I usually have my alignment checked or redone about once a month. For anything other than endurance racing I definitely do not think its worth all the trouble. However if there is play that causes major alignment changes during an endurance race then I could see it being beneficial as a bad alignment will cause excessive wear on the tires which means more time in the pits and more race rubber used as well as slower lap times. In a race where consistency counts and pit stops sometimes determine who the victor is I think the answer is simple. However, how many can say that their car or their needs fit that set of circumstances? -Rob |

Can we see pics of the wheels you use when you bounce off curbs all the time?

Well played sir! ^
(car is looking great) I think it does something, just not THAT tangible nor worth the trouble...sort of like a strut tower brace. |
:iagree: :what:
