slamming R33 GTS with 255's on rear?

[Cake]

I've got an R33 GTS25t coupe, have 17x9 rims on the rear with 255/40 rubber. Suspension is tein height + damper adj coilovers, at the moment the gap between the top of the tyre and the guard lip is ~25mm, i hope to lower it about a further 20 - 25mm if possible so the guard sits just above the tyre or almost level. I have 235's on the front.

Does anyone have a 33 with 255s on the back that is pretty low? Did you have to pull out the inner plastic guard on the front so it doesn't rub when you turn? Also im guessing the rear guards will have to be rolled, anyone got their rear guards rolled successfully on a 33?

Mines a bit lower and is running IMPUL 3 piece on extended width hubs. Take a look at the red 33 on the www.rwdturbo.com sandown track day pics. It's not as low as you might want but I do drive on the street and need some range of motion for decent handling on the track (non adjustable tein coilovers). Then again the offset may be different. I didn't need rolling and the fronts (235) are also cool.

Ive got Volks 17*9 with 255/40/17 and running Tien suspension set on the lowest. It has never rubbed, not lips but was certainly close, but due to the rock hard suspension, there wasnt much travel. I have since raised to the highest setting, yes it looks ugly, but only as i got a canary.

ok thanks skylinegeoff, do you still have your plastic inner guard in? i guess ill just take mine out, my front 17x8 (235's) have spacers so they sit right out but just inside the front guards. my car looks about the same height as yours, maybe a few mm higher at the moment.

Robo's yeah my sus has hardly any travel either, are your guards rolled?

you able to post some pics or pm me, of your car when it was lowered? also how did u go passing EPA with your loud exhaust?

[GTRgeoff]

My inners pulled out overtaking a mustang at 195....uuuugly but no damage to either car.

i had 265's on my old Gtst.. it had plenty of room.

You'll also inherit some nice neg camber when you drop it more, so the tops of the tyres will sit nicely inside the guards.

I've got exactly the same as you....Tein's...17's.....255/40.....235/35. I have all the guards rolled...about $65 each guard. Mine only rubs when turning/dipping, such as exiting my drive (but only at certain angles). Mine is pretty slammed, (see avatar) I can measure if you want.

cheers Ozzy

Ive only got the pic in my avatar on how low it was. At the moment there is a fair gap at the back, so no use sending those, soon i will drop it back down a little.

About the loud exhaust, its amazing who you know in the exhaust industry, so the letter has gone back to the EPA with below 90db.

TO all,

I run 18x9(fr) with 245/18, and 18x9.5(Rr) with 265/18/35 on simmonds le wheels.But be warned dont dump it any lower than 10 to 15 mm above tyre as the ride gets way too harsh,doesnt do the car much good either and you will need to fit a camber kit to get any mileage out of these,as the lower you go the more neg. camber you induce.

are your front or rear guards rolled? im interested in knowing whether it's necessary, since this is the next step to consider if i am to lower it more. yeah got a fair amount of neg camber on the rear as it is.

Ozzy that would be cool if u could measure it and u guys got any pics that show the height?

cheers

Boost, offset is the most critical factor when lowering. A difference of 3mm offset may make the difference between rubbing and not. I am running 18x8 +35 with 235/40/18 and 18x9 + 35 with 265/35/18. The rears are very close to the outer guard (nothing rolling won't fix), but due to stock ride height, they don't rub. The fronts are absolutely fine, could be dropped a fair amount. Be aware though, that a 18x9 +35 might sit differently to a 17x9 +35. Not sure if that is really helping, but my guess would be if you are running 255s on a 17 with the correct offset it should be OK.

[Ronin 09]

not sure if this helps, but here is a pic of how close they sit. I can take some more of it tomorrow from side on if you want me to.

boo5t, measured to the bottom of the guard lip, mine is 630 off the ground all round

[Ronin 09]

Best way to measure is from the centre of the wheel (the hub) to the wheel arch

[Cake]

measured to bottom of guard lip mine is 645mm off ground all round and 345mm from centre of wheel to guard lip. probably as i said before drop it another 20mm, dont wanna get my guards rolled if i dont have to but this may be the only way. the guard lip on the fronts dont stick out as much as the rear, so they may not need to be rolled?

[Ronin 09]

Boost, you really should roll the front, because the time you will rub (possibly catch and pop your guard out) is not when you are going straight, but when you are turning and the suspension compresses. The tyre may catch the metal guard and pull it out - happened on my old car. If you are going to get the back done, get the front done at the same time

BOOST,

Sorry for delay in getting back to you, i ran out of internet hours on sunday nite.Yes my rear guards are rolled,nothing on the fronts.My ride heights are 350mm fr,and 335mm rr, with -1.5deg rr camber and -1.5degfr camber,caster set at 7.0deg and fr toe at 0 with rear at 1mm toe in.The total car weight is 1448kg with corner weights at lhf 394kg rhf 393.5kg lhr 335kg rhf 332kg .Getting these corner weights this even is one of the advantages of running coilovers because you can adjust the corner heights of the car to achieve different weights and even up any discrepensies you may have.The weighing of the car was done on race car scales and done here in adelaide by manta racing (steve cramp )

Hey ozzy can u by anychance send me the photo of your car in the avatar so i can see the ride height etc... Also how much have you lowered it, and is your ride heaps bumpy due to stiff suspension???
