Got A Couple Of Questions Tyres/ Wheels/ R34 Gtt

[Daz305]

hey guys ive got an r34 gtt, with black gtr rims (18x9 +30 i think they are) and Falken tyres 255/40/18 all round.

the front wheels can scrub at times on the plastic guard when close to full lock, which isnt to bad...

The REAL problem is the tyre hitting the cables at the top of the right hand guard. It happens at times when travelling at about 100km/h over bumps on highways... There in a hard plastic shell but im worried about it wearing through...

1. Do any of u guys have this problem? what would you do?

2. I was thinkn of switching to austyre 235/40/18 what do you guys think of these tyres? OR heighten or stiffen my suspension, OR both...

any input would be great... thanks

It looks awfully low .. What eyebrow height is your car running?

I seem to recall SydneyKid suggesting anything lower than about 345mm would compromise handling - maybe try raising it to that level?

yer i've been thinkn the same thing... i was looking at photos of other r34's and its too low isnt it... i think im just used to it so i dont notice... i brought it in december and have never changed it.

i think thats a good idea jrm how do you measure the height is it from the center of the wheel to where?

also can any1 confirm what height is best for handling?

225/40R18's will fix your problem

its not too low....

just cable tie the cables out of the way

i'd change to 235/40s or 245/40s when your current tyres wear out.. 255/40 is massive

Middle of the wheel vertically straight up to the edge of the guard is the 'eyebrow height'.

SydneyKid mentions ride height in this thread: Link

I run mine at 345mm, and have camber kits to keep the camber in check - I like it, handles well, and haven't had any scrubbing issues or too many issues with low driveways / speedbumps (with standard rims).

Apparently anything lower than 345mm becomes a real pain to correct the camber anyway. (It's also the lowest legal ride height for the R34 in South Australia):

To give you an idea of how high/low it looks:

thanks for the responses guys..

JRM - eyebrow height of the car is approximatly 325mm all around... i found a thread with gtrgeoff saying that 355mm at the front and 345mm at the rear so you were right on the money with that.

just curious is there optimal heights for drift?

Hank Scorpio - tyre wise, it used to also do it with my other set of 18's with 235/40/18's.. so ive got my doubts if 225/40R18s wil make much difference...

Joeyjoejoejunior - i cable tied them up a little while ago i dont think i can make the cables any higher.. i cant push them up in the wheel arch anymore i dont think haha

Hekt1k - yes they are pretty big, came of a gtr so it makes sense. but same thign it used to do it with my old 18's with 235/40/18 so i need a bigger solution..

got another questions for ya's. obviously the back tyres need to have fair amounts of grip as they are pushing the car.. but do the fronts need to be that sticky? i have never had my car understeer if anything it will oversteer so do the front tyres need to be that good? would 235's or even 225 make any difference to handling of the fronts compared to the giants there atm

cheers

its a hard question to answer which depends on the purpose of the car.

you drifting before. if thats the case then you want hard suspension and traction really isnt as important as someone who is after drag/track.

i highly doubt a upgrade to 235s would change anything. the reason your car oversteers is because of your rear suspension/tyres.

[Daz305]

id like to have it all but thats not how it works i guess haha.

if i had to choose one id choose drift.. meaning the car is probablly set up well how it is...

looking again under the front wheel arch there is a small gap that i may be able to shove the cables up into...
