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?

    • Lucky man, who owns it in the family? Any pics? 
    • The engine stuff is Greg Autism to the Max. I contacted Tony Mamo previously from AFR who went off to make his own company to further refine AFR heads. He is a wizard in US LS world. Pretty much the best person on earth who will sell you things he's done weird wizard magic to. The cam spec is not too different. I have a 232/234 .600/603 lift, 114LSA cam currently. The new one is 227/233 .638 .634. The 1.8 ratio roller rockers will effectively push this cam into the ~.670 range. These also get Mamo'ified to be drilled out and tapped to use a 10mm bolt over an 8mm for better stability. This is what lead to the cam being specced. The plan is to run it to 6800. (6600 currently). The Johnson lifters are to maintain proper lift at heavy use which is something the LS7's supposedly fail at and lose a bit of pressure, robbing you of lift at higher RPM. Hollow stem valves for better, well everything, Valve train control. I dunno. Hollow is better. The valves are also not on a standard valve angle. Compression ratio is going from 10.6 to 11.3. The cam is smaller, but also not really... The cam was specced when I generated a chart where I counted the frames of a lap video I had and noted how much of the time in % I spent at what RPM while on track at Sandown. The current cam/heads are a bit mismatched, the standard LS1 heads are the restriction to power, which is why everyone CNC's them to get a pretty solid improvement. Most of the difference between LS1->LS2->LS3 is really just better stock heads. The current cam is falling over about 600rpm earlier than it 'should' given the rest of my current setup. CNC'ing heads closes the gap with regards to heads. Aftermarket heads eliminate the gap and go further. The MMS heads go even further than that, and the heads I have in the box could quite easily be bolted to a 7.0 427ci or 454 and not be any restriction at all. Tony Mamo previously worked with AFR, designed new heads from scratch then eventually founded his own business. There he takes the AFR items and performs further wizardry, CNC'ing them and then manually porting the result. He also ports the FAST102 composite manifold: Before and after There's also an improved racing crank scraper and windage tray. Helps to keep oil in the pan. Supposedly gains 2% power. Tony also ports Melling oil pumps, so you get more oil pressure down low at idle, and the same as what you want up top thanks to a suitable relief spring. There's also the timing chain kit with a Torrington bearing to make sure the cam doesn't have any thrust. Yes I'll post a before and after when it all eventually goes together. It'll probably make 2kw more than a setup that would be $15,000 cheaper :p
    • Because the cars wheels are on blocks, you slide under the car.   Pretty much all the bolts you touched should have been put in, but not fully torque up.   Back them off a turn or two, and then tighten them up from under the car with the wheels sitting on the blocks holding car up in the air.
    • Yes. Imagine you have the car on the ground, and you mine away all the ground under and around it, except for the area directly under each individual wheel. That's exactly how it'd look, except the ground will be what ever you make the bit under each wheel from
    • Yes, if you set the "height" right so that it's basically where it would be when sitting on the wheel. It's actually exactly how I tighten bolts that need to be done that way. However....urethane bushes do NOT need to be done that way. The bush slides on both the inner and outer. It's only rubber bushes that are bonded to the outer that need to be clamped to the crush tube in the "home" position. And my car is so full of sphericals now that I have very few that I need to do properly and I sometimes forget and have to go back and fix it afterwards!
