  3. 600Ti lowered suspension issue

600Ti lowered suspension issue

I had my Ti lowered about last September and 17" rims with 215/40s fitted. The only modification to the suspension was the springs, which were described on the invoice as "H+R Springs (23mm)". I don't know what the 23mm refers to, or how much the car was lowered.

Anyway, I had new front tyres stuck on the other day (new alloys *still* aint arrived) and there was some pretty severe wear on the inner edge of the tyres. On the passenger side, we found that part of the suspension had been rubbing on the tyres (and gouged out a fair chunk of rubber all the way round, for that matter!).

For what it's worth, there's a picture of the bit it's rubbing on:

It's not rubbing on it all the time, but it evidentally is sometimes. On the driver side it's not rubbed on any part of the suspension at all.

It could be that most potholes, manholes, and general dips are on the passenger side of the road, therefore when the dip is over a certain severity the tyre hits the suspension.. or perhaps there's something up with the suspension on that side (I did hit a curb a couple of months ago!).

I also notice that sometimes when I turn right at near full lock, there's a brief kind of scraping noise.. it's never happened when turning to the left. I'm not sure whether that is it rubbing on the suspension as in that picture, or something else:

(just to give some idea ofthe clearance between wheels & arches) Furthermore, the new alloys I ordered with 215/45's on, as I would prefer that little bit more rubber there and they don't throw the speedo out as much. However, that would likely exacerbate these problems. At the moment, with the new tyres, I'm treading carefully, so to speak.

I need to do something, and especially before I put the new wheels/45 tyres on, but what? Have any of you guys has these issues with your lowered Ti's? Could it be I need some shorter shock absorbers on the front or something? Or perhaps the car was lowered a bit too much? Should I get the passenger-side suspension checked out, or is it likely just that it's met with more potholes?

Any help appreciated!

go to 205 tyres, 215 is to wide for the car. Woudl prob save a fortune on tyres to.

Would 205's fit on the same wheels?

Welcome to the world of lowered cars :) By lowering it, you've messed up the suspension geometry - hence the dodgy tyre wear.

What offset are your wheels ? They're prolly ET40 like mine, which is too low - you should be running ET45.

It's quite likely that is the source of your rubbing then :)

Agreed.

Again, what offset are your wheels, both new and old ?

Your local Rover dealer will do a full four-wheel suspension geometry check and adjustment for £49 plus VAT - it's prolly worth getting it done.

Incorrect.

215/45/17 tyres are correct for a 620 TI - work it out yourself if you don't believe me (stock tyres are 215/55/16).

Wierd - you've got rubbing on the INSIDE ?

Wheel offset still required :)

Yes, but they're the wrong size :)

I thought someone was going to say that ;-)

Hmmm.. I don't know to be honest.. how do I find out again? I thought offsets were to do with the placement of the holes for the wheel bolts.. the new wheels are due this week.. I just told them they were for a 600 Ti, so presumably (hopefully) they will supply the correct offset.

So, can suspension be adjusted to give more clearance?

You ask the people that sold you them ! If you're lucky it'll marked inside the wheels - mine are.

No, that's the PCD. Offset is how far in/out of the arch, the wheels fit. The bigger the offset, the further into the arch they go.

Unlikely - most places have ET35 or ET40 in their books for the TI, and this is wrong. You'll get scrubbing. They need to be ET45.

Not really. But if it's way out, is may cause rubbing and/or dodgy tyre wear, so you should get yours checked out.

ET42 should be just about ok - cross your fingers !

I mean, stock tyres are 205/55/16 :)

If they still catch you could get 3mm spacers for the front, I'm not a fan of using spacers but you should be able to get away with 3mm without a problem.

That might be an idea if I get desperate.. I still think something might be up with the suspension on the front passenger side though.. that scraping noise that occurs when I turn right on full lock doesn't happen on the driver side when turning left... hmmmm.. going to get the Rover garage to check it out a week on saturday, when they look at my SRS system.

Yes, assuming they catch the inside of the arches. Trouble is, with a 3mm spacer, you lose the hub-centric nature - space covers the "sticky out bit" of the hub, so you can't locate the wheels properly, and they're held in place purely by the bolts. Not good.
