poly guibo E30, E34, E36, Z1, Z3

[e30euro]

well if you were to compare a normal guibo to this poly guibo you can see a big difference this poly guibo is much thicker as well as stronger. compare a set of control arm bushings the stock ones are gapped and softer as the poly bushings are a full thicker bushing at a much harder compound making it last longer and is much stronger.

it is poly its very good though

All poly is not created equal. What is it?

What is it? What is the durometer rating? Poly can be softer then the stock rubber, or as stiff as aluminum. I don't want either in my drivetrain.

That's not even remotely true. Thickness has less relevance to strength that the actual compound. That's not something you can see with your eyes. I'm not trying to bust your balls, but if you want to sell a product like this you may want to be able to address the technical details.

it is true as i have built suspension and installed bushing kits many of time as i can only tell you this guibo is hard as a rock no soft at all from the one i had seen was like a rock and very very strong.

straight poly is surely not a good material for this part... The stock part is rubber heavily reinforced radially with fiber. It flexes a lot, copes with vibrations and it was designed by an army of engineers so well that it is used in nearly every bmw. Its cheap, hella durable and stands plenty of power. Please describe this part's making, and benefits as i see none.

u know what im sick of people craping my thread u have a problem pm me other than that i would like those posts deleted thanks

if you also dont want it dont buy it easy as that ive seen this product in action and its bad ass u dont like it dont write anything

haha


Just because it carrys the name "polyurethane" does not mean anything.

The stock rubber guibo is much stronger then many grades of poly.

Seeing how far you can push your fingernail into it is not a valid strength measurement. You'd need to measure the deflection under circular load of the poly vs the reinforced rubber, and measure wear over time.

I sure hope it's not "hard as a rock". The goal of that part is to absorb drivetrain impact. It's a pretty cheap part compared to the rest of the drivetrain. And with a properly balanced driveshaft, it should last a long time.

If you were able to give us a durometer measurement of the poly, it may make it valuable...

I was interested until I asked for details and you tried telling me it doesn't matter and that it's just "better".

[e30euro]

as i had said on the first page from my example read a whole post before writing anything

just say you don't know the hardness of the poly stop beating about the bush, you're less informed than the people asking the questions so you end up sounding silly.

This... my point I was trying to make. I wanted to understand how this was better.

Great selling technique.

[DivineStyler]

I needed that like months ago... lol... Good luck with sale!

This reminds me of that FS thread for bellhousings with the douche that was like "if you don't know what this is for, GTFO."

OP, with this kind of attitude, you won't sell anything.
