Sorry mods but the car is on the ramp now!

Having Prodrive springs fitted (red ones) to an 03 STi at the moment and the fitter says the bumpstop that is in the box will not fit into the shock. Is this correct or is he being a twonk!?

He has all the pProdrive instructions with him!

My prodrive stuff came with a note which said something along the lines that you would need a different part number for the stops.

Philip Attaway

seems odd to buy springs specific for the STi and then have to order another part

chris's scooby

Would you like me to go to my car and have a look for the note with the part number?

Phil

That note is for attaching to your service book so that if and when you replace them you use the same bit that is included in the box

My ones were fitted at TSL and were fine

Might be a bit late now but tell him that the bumpstop fits inside the damper as per the fitting instructions.

Thanks Mike,

I have picked the car up and they have not been fitted (new bumpstops)

Will this affect the ride or the springs doing their job?

The car feels and looks much better and the geometry has not even been done yet

Because the shock absorbers are "upside down" within the strut body, the bit you see when you take the spring off is not actually the piston rod but the damper body. The piston rod is out of sight hidden inside the strut body.

Your mechanic will have taken the spring off and tried to fit the new bumpstop over the outside of the damper body which he could see (and which to be fair would be the piston rod on 99% of cars not fitted with upside down shocks). If this is the case then not too surprising it doesn't fit.

He needs to strip the damper out of the strut to get to the piston rod and presumably fit the bump stop there. Basically he needs to RTFM......

If the new bump stops were not useful then I hardly feel Prodrive would have gone to the trouble of supplying them and making the spring fitting so much more difficult than it would be for just springs. Quite sure it'll be safe and OK to drive for the weekend without it but you just won't get full benefit of the mods.

As you're lowering the car presumably the old bump stop is too long so I guess the car will be riding on it most of the time. The new bump stops will probably be shorter but less compliant so you are further away from them in normal use but they end up giving the same bump stopping over less distance.

Can I have a job Mike, or am I talking bollocks?

chelspeeds ya spot on m8 i fitted my mates the other week and you have to take the damper apart as the bump stop as you rightly said is inside the damper body at the bottom. pull the old one off over the end and pop a bit of grease round the new one and push it back over then slide it back in the damper body. you will notice the old ones a quite a bit longer and not as stiff(this sounds like the script for a film i got off me m8 dave)

Yes, he's a twonk!
The bumpstop is internal and if not changed for the smaller version you may experience bottoming. Do you think Prodrive would supply this plus instructions if it wasn't necessary?
I've done two 03 STi's now (mine and my sons) and changing the bumpstops is not a problem.
While your at it, make sure he's re-fitted the top spring seat properly, there are three holes in the seat, they should be towards the outside of the car, i.e. the wheelarch.

Thanks for the info

I am off on hols next week but will get him too re-fit when I return.

There is a slight rattle from the offside rear shock now to which I wan't them to look at.

stockcar

think its probably even mentioned how to fit in the destructions that come in the box................
