i gotta buy new tyres for rego an thought since im dishing out money i may as well get tyres that dont spin everytime i hit boost. what have you guys found to be the best street slicks, an if you have any links to supplyers web pages?

there are known gotchas when using semi slicks on the street - buyer beware

you obviously have some issues if you are have that much traction issues - i suspect there are other issues

semi slicks are approved for American roads, not australian. may get away with it, maybe not? and absolutely no good for the wet

why are they no good for the wet? have you ever driven on some? what about wet weahter specific semi slicks? isnt the tread only in the tyres for wet weather driving anyway? im no tyre expert but ive driven an FC3S with wet weather specific bridgestone potenza 595 S something semislicks in the wet and they were mental

and also correct me if im wrong, but dont the lotus elise and or exige that are available as a road going vehicle in australia come out of the dealership with advan nevoa (not sure of the exact model) semi slicks?

yes they do, but that doesnt make them good in the wet :glare:

better off going for a tyre like the kuhmo ecsta

obviously this would be better in the "Suspension, braking and tyres " subforum :D

I used to drive around on semi's all day and every day.

they are legal for on the road as far as i'm aware, as they are dot approved,

in the wet, it was often hard to lose traction in a 450hp gtr And in the dry... forget about spinning your wheels anywhere, even 7000rpm launches all you got was stick.

Now the bad points,

They will be alot harder on your drivetran, you could possibly even break things, your diff is going to get a worn out alot quicker and the tyres themselves dont quiet last that long..

this was bridgestone re55s or similar.

These guys give me 1.54 60 foot times and are street legal, so they are my everyday tyres. Just be careful with skids as i have used a pair in 8 quarter mile passes showing off. They come in plenty of sizes too. More grip in the wet than my old street tyres because of the compound gripping, but as i dont run them on the front aquaplanning is not an issue.

They don't like corners very much, but great in straight line.

federal 595rs or falken azenis rt615 seem to get good reviews... treadwear rating is like 180-200 for both so not too low. also they'll disperse water better which is good for a street car.

Don't use semi slicks on the road.

Why?

Because they are, in no particular order:

Noisy.

Stiff in the sidewalls which gives you a harsh ride.

Expensive.

Short lived.

Pick up every stone etc on the road & fire it into your paint.

And, um oh yeah A WASTE OF MONEY

A semi slick needs temperature to generate its grip properly. Other than driving like a complete fkwit on the road you will not generate these temperatures.

So you will never get the gain out of the tyre you wanted.

Just go and buy some good road tyres.

yeh the camber on my rear wheels is out, im gonna buy ajustable camber arms of ebay http://cgi.ebay.com.au/REAR-Upper-Mount-Ad...1QQcmdZViewItem

have any of u guys used these items before? what do you think of them?

As is quite common, the traction problem is not tyres. The usual suspects, lowered too much, too high a rear spring rate, no rear subframe alignment or camber correction. Simply replacing the upper control arms will only partially fix one of the problems and introduce yet another, bump steer. You need to correct both the rear upper control arms and the traction rods to avoid bump steer problems. There are better alternatives for fixing this problem than replacing the arms, try a Rear Camber Kit from Whiteline or Noltec.

true to that Sydney kid...

I recently did a full comprehensive alignment on my 180SX at Wholesale Suspension after I installed new bushing in the front end on my own and decided to align every part I on the car.

Just after the alignment alone, I noticed less bump steer, more grip, less to zero tyre squeal around corners and mind you this is with just shietyy yokohamas.

For street use, don't bother with semis, unless you're going to track it, I would save the money and get offset bushing to correct camber on the front and rear and get a good alignment.

i.e. don't bring it to Bob Jane, or your mainstream shops, they're not capable of adjusting camber...

I asked, they said they couldn't do it.

They can do it just fine. Once you tell them you don't care about tyre wear and you won't be back in 2 weeks complaining about bald inner edges they will do what ever you ask for.

My local bob jane adjusts my front and rear toe, front and rear camber and front caster. I wouldn't expect them to have the time or the gear to corner weight or adjust traction rods so i don't ask. It's the difference between $500 and $50 alignments

back on topic. I run rs595's on the front and rt215's on the rear. It's a waste of money, except for the odd time i get to the track and it's too wet for proper semis. If you have an aggressive alignment you will destroy the things driving on the freeway anyway.

As mentioned by djr, don't run a proper semi on the street either, they need heat to work properly, when they aren't hot they are worse than nankangs and will have you up a gutter before you know what happened. It happened to me when i was young and naive, i have a $250 rim repair bill around here somewhere to remind me not to be so stupid in future ;)

i found a whiteline rear camber kit on ebay an im gonna give it a shot an see if a can get any better traction, but i dont fully understand how the kit works could you give me a rundown?

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
