172 Ph1, 2 and 182 subframe difference?

[Stu-]

Does anyone know of the difference between the 3 models?

I know of the dog bone mount being slightly different but is there any other differences?

 

[Stu-]

Also forgot to add, does the caster differences come from wishbone or subframe?

PH1 - 2.15
PH2- 1.5
PH2 cup- 3.0
182/ 182 cup- 3.0

No one?

There's quite a lot of info in the search function.
I know the wishbone bolt holes on the cup subframe sit further out giving a wider track.

Pretty sure the wider track is from the wheels having lower ET and nothing to do with subframe or wishbones.

They are further out than a phase 1 subframe.

Been covered. The Cup subframes wishbone hole position, wishbone balljoint position, and wheel offset were all different from the other 172's out the factory. As far as I knew the 182 cup and full fat shared the 172 cups setup but I don't know about a normal 182.

So between the ph1 and none cup ph2, it should be the same?

Subframe is still different mountings on the wishbones

Only reason I want to know is, I fitted a ph1 subframe to my ph2, and ever since I've had a driveshaft knock when cornering, lined the engine mounts up best I could and it made it better but it's not gone away! It wasn't there before and the only thing that was changed was the subframe. I've bought a proper ph2 one now so I'll get that fitted and hopefully sort the problem out.

 

[Dan@SJM]

Or fit ph1 shafts

Or fit ph1 shafts

Bought new sub frame now so see how that goes haha!

 

[Ph1 Tom]

Ph1 21mm land on wishbone mounts, Ph2 16mm, cup 11mm.

Cup shafts are the same length as the normal ph2 shafts but are one piece instead of equal length. Ph1 are 20mm shorter and one piece.

Tie rods are different too, cup ones are 15mm longer, all the others are the same.

Cup wishbones have extra caster although Renault don't sell the non-cup ones anymore. You can modify the hole positions for even more caster too.

Thank you! So this is why I'll more than likely be getting the driveshaft knocking under cornering?

I'll be fitting the ph2 subframe sometime next week so I'll let you all know if it fixes it. Thanks for all the help y'all!

 

[Ph1 Tom]

Yes it'll be bottoming out.

May as well fit a cup one, you'll get a little more camber from it as the holes sit further out.

I've already bought a normal 172 one but cheers for your help.
