Tyre scraping

[MicrAde]

Ok, so I have a 99 k11 that is lowered at the rear on std springs with 2 coils removed and corsa shocks. The axle shift has been (slightly over)corrected with frankstyle offset bushes.
Now, the issue is that, when 'pressing on' particularly through fast left handers, if I hit a bump the o/s/r tyre is making contact with the, admittedly unrolled, wheelarch. This issue is a hundred times worse with a rear seat passenger
I am currently running 5.5x15" alloys, ET45, wearing 175/50x15 tyres and my plan is to go a little lower and space out the rear wheels 20-25mm, obviously this will exacerbate the problem.
Short of never carrying passengers/a load, or fitting back breaking, teeth rattling polo coilovers how, if at all, can I avoid/minimise the tyre to arch contact?
Would replacing the cut std's with cut lowering springs improve matters? Or how about replacing corsa hydraulic shocks with gas shocks?
Stupid rear suspension design
Thanks in advance peeps

I'd invest in a panhard rod and stiffer springs
Stiffer springs at least with only happening on bends/body roll.
Shocks won't affect much in this situation

Get a panhard rod, roll arches. Corsa rear shocks and cut standard springs seem to compliment well, cut lowering springs will help a bit but be more uncomfortable. You can get up to a 75mm drop on corsa rears and cut stock springs (3 coils off if you know how to fit the shocks to make them shorter)and still be fully captive, cut lowering springs will have less sag and it will sit higher because they are stiffer.
But yeah, panhard rod first, if thay fails roll the inner lip, and flair arches if all else fails.

Cheers Andy, a Nodspeed rod is on my wishlist for when funds allow, although as I say, at the moment while standing with no load, the axle shift is slightly overcorrected. Any recommendations for springs? Would cut lowering springs be stiffer if I removed the softer, tightly wound, coils on each end?

Roll the arches. And give the tab that the final bumper fixing attaches to some attention.

This guy knows.

Defo gonna have to roll the arches I think but I dont have the lows/rims to pull off flared arches

 

[Enuo]

have you rolled the lip?

 

[MicrAde]

have you rolled the lip?

Not yet but the tyre is miles away from it. When I roll it that will improve things, until I space rear wheels then its back to square one Its all about the stupid axle shift on compression

Thats how I did them on the k10 Is the headband compulsory??

 

[Enuo]

it'll still shift on compression with a noddyrod

I know, thats why I emphasised the fact that at the moment it is slightly overcorrected. Guess its just a case of going stiffer Who needs ride comfort anyway

Any set of lowering springs will do. If you cut the tighter/stiffer coils off one end you'll still end up with a stiffer than standard spring which will be just enough

just go easy til you can afford a noddyrod, much less hassle than the other options. Unless over corrected means going lower will aolve the problem

Absolutely.

Go easy?? Wheres the fun in that? Going slightly lower will bring the axle shift back level, ie equal side to side, but it looks like stiffer is the way to go Better tighten the front end up a touch too

 

[MicrAde]

Thanks for all of your input guys

 

[MicrAde]

Now, anybody selling any lowering springs (really) cheap?? Don't even say it Andy

Awww whatt... can't deny me my entertainment

Go on then.................cos I would!

 

[h701micra]

Well if you insist

Better tighten the front end up a touch too

I will reserve my comment just remember you said it... not me

You cheapskate ... you knew that was coming

Come on Andy, no need to be gentle with me!

 

[MicrAde]

Come on Andy, no need to be gentle with me!

That sounds soooo wrong

 

[Enuo]

Just chop another half coil off your stock springs, problem solved. Free as well, except for the 2p's worth of electricity...

I need not do anything .... doing alright all by yourself whilst I look the victim
