Review. Atomic MR-03 Front suspension Lower arm set

The parts came in the usual Atomic clear plastic bag.
Included in the package was mounts for wide and narrow front, and all other necessary hardware for mounting.
Also, it included a user manual. Great!


Mounting is super easy. First you remove the original bottom plate.
Then you fasten the front and rear part of the kit. 
Now you mount the middle section. This is what makes this mount great. This makes you able to change out the tie rod with only removing two screws, and not remove the whole front end.

The fitment is great. Everything align perfectly. No modification needed at all.

I mounted this with the Reflex Racing extra long king pins. They popped right in, without any binding what so ever. No exess movement in any way either.

Now I come to the not so good part.

Everything worked flawlessly for about 10 - 15 hours of runtime. Then my car started to behave inconsistently. Slowly it went from neutral, to really bad oversteer on corner entry. It took me some time to understand what the problem is. See own article here: Inconsistent car

The king pin sockets did wear out incredibly fast. Now the king pins has about 1mm play up/ down, and this can not be shimmed out in any way. That is why I do not use this lower arm kit any more. Other than the rapid wear, I love it. Very fast and easy to swap tie rods. Light weight. Very flat and precise mould. But wears out to fast for me. The stock mounting plate has over 100 hours of runtime on it, without any noticeable wear.

Hopefully this was a bad unit. If not, I hope Atomic will come up with this product with another plastic or composite material that can last a bit longer.
