Where to begin... hmmm.



The car set up i guess. MY98 Terzo, 18" speedline GT1 Wheels, ET48 offset, 225/35/18 AVON tyres, KYB adjustable shocks with Eibach springs.



Until recently i was running standard shocks with Eibach springs and 225/35/18 Toyo T1s. To make the tyres contact with the arches there needed to be 5 people in the car and be giving it some round corners. Now with 4 people in the car i have to corner like a granny in a 30 year old mini. I can also make the tyres catch the arches with just me in the car cornering 'fairly' hard!



I’m wondering firstly why suddenly the tyres are catching the arches and secondly what I can do about it. I've tried setting the rear shocks to the stiffest position but it makes no difference really. Do i have the correct wheel offset? Can there really be such a difference in the width of the tyres from manufacturer to manufacturer? are the new shocks contributing to the problem at all?



One suggestion i had is to have the wheel arches rolled out? Will this solve the problem? Do I really have to go to the expense of having this done or is there another solution?



Apologies for the slightly jumbled post, I’m in a bit of a rush but wanted to get other peoples opinions and thoughts.

Looking at the tyre manufacturer web sites the tyre widths come out at 230mm for the Avons and 231mm for the Toyos ! Presuming they are both 225/35/18s... So if just the tyres changed the Avons should have been marginally better.

I have a MY00 with ET45 wheels but can only run 215/35/18s ( and then had to remove the wheel arch liners ) - Perhaps you need a ET50-52 offset to get away with a 225 - although if you were running those happily before... Has the suspension been re-aligned after the shocks were fitted ?
Not sure from your description if just the tyres were changed and the rubbing started.

225 tyres are too big for a classic, you need to run either 205 or 215, probably in your case, 215.

i was just about to post a similar thing i am running 18" wr1 replica wheels on a 98 r reg wrx and under acceleration and cornering hard the rear arch rubs would the smaller tyres and (or) stiffer suspension help!!!!!! please help

Only the width of the tyre (reducing) would help, if you get rubbing, you have to consider the worse thing that could happen due to excessive wear, and thats a blow out

...closely followed by thumping a hole, the tyre smacking the arch bending the metal slightly, paint cracking, previously mint impreza now with rusty wheelarch in a vauxhall stylee...

so with 205 or 215 tyres would it make it better or would it be better to lower and stiffen the suspention

tath

lowering? maybe heightening would. if it's definitely the arches and not the inner body, then rolling them will give you an extra cm or so - plenty! just don't get it done cheaply by some pikie.

Thanks for the replys chaps.

Jim, i had new suspension and 2 days later new tyres. Interesting to learn that the Avons are very slighty narrower. I had the geometry set up after they were fitted does that count? it's happening on both sides so i guess it's ok??

When i first bought the car it was running 225/35/18 pirellis - no problems there whatsoever.

I really really really don't need any more expense at the moment damn thing cost me a fortune recently. I did consider buying some 215's but i jut shelled out £450 on the Avons

So basically my options are :-
get the arches rolled out -£300
get a set of 215's Approx £400
or get a new set of wheels at god knows what cost, the added problem with new wheels is i have godspeed 355mm disks on the front so the options there are very limited and costly

ARRRRRRRRGH!!!

Tony, had that very same thought, a blow out just driven 3500 miles to Spain and back with a boot full of stuff and 4 people in it, the tyres are surviving pretty well considering.

You could remove the rear arch liners - if you havent already. That may give you a couple more mm. I'm not sure you'll find any wheels with a bigger offset at a reasonable price - even then you may just move the rubbing to the inside ! Guess you could see if you can sell the 225s on here and get some 215s ?
