Question Fitting STI torsion bars to a WRX

I will soon be fitting a genuine STI spoiler to my WRX and have read, in various places, that uprated torsion bars need to be fitted to avoid the boot lid crashing shut because of the extra weight of the STI spoiler.

I already have a set of torsion bars from an STI but has anyone got any advise, pointers or a guide as to how to fit them?

I've heard they can be difficult and assume this is due to the torsion aspect.

thanks

The car did have a replica STI spoiler fitted for around 9 months but was removed recently due to a cr@p paint finish and cracking. I never had any problems with the boot crashing shut but I do know the replica spoilers are lighter.

Maybe I'll try the OE spoiler with the standard torsion bar and only change if it's a problem.

Has anyone else got different experiences to WRX_Rich?

The OE STI spoilers been on the car for 2 weeks now and although I agree it stays open with the standard torsion bars I'm considering fitting the STI versions to provide a dampening effect when closing the boot.
The boot lid is much heavier with the STI spoiler. The wife "forgot" the other night when shutting it and it crashed shut with such force I'm surprised the rear wheels didn't fall off

Has anybody got any advise or tips for replacing the torsion bars?

I'd rather do it myself if possible to avoid visiting a garage.

I had another look and finally worked it out.

Held the boot lid open with a piece of rope running around the under side of the boot lid and then through the open back windows.

Then used a strong screw driver to lever the torsion bar away from the boot hinges. There's metal brackets attached to the hinges which then fold flat reducing the torsion to almost nothing.

Used a rubber hammer to gently knock the old torsion bars out and fitting the new ones was the reverse of above.

The boot lid now shuts as it should (ie doesn't crash shut) and I would certainly recommend fitting them if upgrading to a heavier OE STI spoiler.

where is the best place to get the torsion bars, do they have to be genuine or does anyone 'do a copy'.

I am have in the DR Motorsport Replica STi8 spoiler delivered soon, which is exact size and weight as the OE Subaru one...

Cheers
Rob

I used to have a replica spoiler from DR Motorsport fitted and it wasn't as heavy as the OE STI version. I don't think you will need to change the torsion bars with yours.

By the way the torsion bars are available from Subaru (listed on thier Web site below) and are £30.
