34x11.5 on a SWB GQ

[DB]

What are the chances of fitting 34x11.5 tyres on a SWB GQ.
Got 2 inch spring lift.
Is a guard cut or body lift deffinately needed, or can I get away with it with minimal rubbing.
From what I hear large tyres seem to rub even with large lifts?

If they are JT2 34's, I ran them with a 2 inch lift. Had to remove the stock flares and add flexi flare. Only rubbed on full compression. YMMV.

correct - 33MTRs rubbed with my 6inch lift.

thats because u didn't extend your bumpstops

same scenario, exactly,

BIG RED TOY, extending bumpstops sounds good, but what a waste of lift if you are going to restrict it,

thats "you" hving spring over with 8 leaf packs all round, whats the point?

WRONG!!!
i don't have a spring over , the point of longer bumpstops is to limit the downwards travel & having the longer springs allow 4 more upwards movement, therefore keeping your wheels on the ground

i used the spring over with you as a comparisson, cause i believe you were looking into, it, now, how do bumpstops limit downward travel? and how do having longer springs allow for more upwards travel, are you confused?

[ozy1]

what you were trying to say was, having longer bumpstops will limit upwards travel, and having longer springs and shocks allow for more downwards travel, upon saying this, my rear springs at full droop, have about an inch left in them, but my shocks limit this, if i had longer shocks, my springs would fall out without retainers,

[Big Red Toy]

i'm not confused, i know exactly what i'm talking about. The longer bumpstop limits the amount of travel downwards, as the bump stop hits the housing. A Taller spring stretches more & therefore giving u more travel, suitable shocks are required. Shit if u can't understand that u might as well sell your 4b and buy a commodore

Can anoyone make sense of this future commodre owning fool........................

Think about it , why else would longer bumpstops be sold?

[ozy1]

to reduce up travel, on the compression stroke, and to help prevent shocks from over compression, farkin the seals,

form the sounds of it, youd know about farking seals,

OK big red toy is smoking the good stuff tonight.

If you tyres are rubbing the suspension is not going any higher. All you are doing is buggerizing the inside edge of your tyres and wearing the paint off. So lift/lower your bumbstops.

I tested mine the other day and the 35's on my shorty start to rub about 30mm before the bumpstop hits. But I can get the bump stop to hit.

[kc_ksom]

I know what your saying big red, I don't think the others know but, lol....

If you fit taller bumpstop rubbers, the tyre will be stopped before hitting the gaurd, so it will stopping the downstroke (big red is correct)

eg....
1 ton weight on the front of the car, car goes down from the weight, and this will then bring the bump stop closer as the suspension is compressed untill it hits the bump stop rubber, then it dont matter how much more weight you have in the front it wont go down any ferther...

Therfore if you have taller bump stop rubbers, more clearence will be in the wheel arch because the bump stop rubber was raised,,, can you's understand that clearly, this was a little lame eg but you should be able to work it out...

Hope this has helped..

[kc_ksom]

After thinking about it you can class the down travel of the car as up travel on your suspension..

Therefore the upwards travel of the suspension will hit the bump stop earlier, either way you want to put it, TALLER BUMP STOPS WILL ELIMINATE TYRE SCRUB

Yes you will need to take off the factory flairs and cut the gards. I was in the same boat as you and ran the tyres without a gard gut and it was sh*t house off road as it was rubbing when i hit even the slightest of bumps.
