Hi guys, how is everything?
I have just upgraded my G40 with a Blistein B12 suspension kit and I have one question
In the front side, do I have to put bumpers? I mean some kind of rubber bumpers in the suspension?
Bc the kit doesn't come with bumpers and I don't know if it doesn't need bumpers or do I have to put them?
Can anyone help with this?
Many thanks in advance!

Yes you really do need bump stopa

Hi Pete,

Here people say that the front suspension has the internal bump stops
What do you think?
they're all talking about different shock absorbers on different cars though, I would ask wherever you bought them from.
The front polo bump stops are just these:

I can see no harm in just using them as well assuming the piston rods on your B12s are the same diameter as normal polo shock absorbers.

Those are the OEM bump stops
My supplier told me that as far as they know, I don't need to put bump stoppers bc the suspension has its own bumper stoppers inside the suspension (as far as they know doesn't look very reliable lol that's why I asked you)
Also the people say in the URL the same as my supplier, that they have internal stop bumpers
The thing is that I already installed them...so putting a stop bumper is a lot of work...
