Vejam como, e pedia aos moderadores um sticky visto ser uma ajuda para todos os E30s também:

Jeroen from www.bmwe21.net Escreveu:The 320iS uses the same subframe as any stock E30. There are already known problems with the subframe not coping with the 325i enige on top, let alone with the 320iS's more powerful and definitely more vibrating engine.

For the car of a friend of mine this has led to the engine mounts (which are 'ears' welded to the subframe, not the strongest construction) slowly being torn off the subframe... noticeable through rust at the seams.

So... we decided to go for a used subframe and modify it:

sandblasted subframe

Then.. fitted a Turner Motorsport subframe reinforcement kit:

inner reinforcement plate

inside of the ear welded as well, on top of the original welding seams on the outside

outer reinforcement plate

and zinc covering the whole subframe now

Now it's time to add some primer (if necessary?!) and paint the subframe black again.

Please note that any E30 subframe will suffer from this if the car is equipped with a strong engine an/or used in a thorough way. I'll start a search to build my own now...

Last but not least... this is my buddy and almost neighbour Folkert who took care of the sandblasting and the welding... what kinda chassis needs that much welding... it's a french car! :twisted: He drives a 325iX himself though... in the process of being track prepped. BTW he's also the guy that did the welding on the cage fittings for my track car.

Many thanks Folkert!
