I have a tiptronic RS200 without a LSD, so i'm finding a few occasions where i'm spinning one rear wheel up coming out of tighter corners etc.

The obvious solution would be to get one from a UK sport, which i guess will be the same idea as the one in my AE86, does the job without being that harsh as opposed to an aftermarket one which in AE86's at least are a bit more brutal in their action. what do people have in their cars, also what would the going rate be for a Sport LSD ?

On a similar vain, the suspension on the car feels not that well controlled, sometimes harsh over poor surfaces but a bit bouncy over undulations. I don't know if this car has standard components on it or not, elastic band tyres on the 18" wheels aren't helping either i know. How does standard RS200 suspension match up to UK Sport ? It may be that the poor roads near here dictate changing to something a bit more suitable.

As a new owner i have a few more questions, but i'll get to those at a later date :winky:

rear tyre pressures?
get the rear shocks/suspension checked out
you could also try fitting new sways all round - uprated ones i mean
Red Panda
Anybody have any comment on lsd's or is this better posted in the main section ?

You could be right about tyre pressures, new wheels coming so i'll sort it out then

cheers

i found mine was suffering with the same problom . i solved this the old "why use a scalple when you can just nuke them" . way

i got a cusco suspension zero ze along with a fcon and front and rear strut braces

i find a huge difference . when they replaced them they told me my old suspension's springs were on the way out and that was probably causing all the probloms
edit//
forgot to say changing out the suspension of my car i should of done first . i realise that now . the car totally is different to the way it was . it has to be the best thing ive done for the car as yet

at the risk of making my self look a fool im going to ask this question. Dont the altezza's come with an LSD as standard?

Welcome to the loc mate not all of them come with one heres how ull know
on your in plate (located on the bulkhead)u have a load of codes
Look for the codes
ao1a-no diff
ao1b-have a diff
ao2a-no diff
ao2b-have a diff
so if this code ends in B it means u have a diff

best of luck :winky:

The LSD is really worth it in a powerful car. I put an RS200 LSD in my Supercharged IS200. It is not brutal, you can only sometimes notice a soft shudder though when it starts to do its work and transfer the torque to the outer wheel.

The problem really is to find one. New they are ridiculously expensive, and used it's anyone's asking price. I got lucky. Maybe you can find one at a breakers, but they'll be hard to find.

What about the standard UK sport LSD, is it up to RS200 power ?

I have just come from owning a 97 Integra Type R. The handling on the integra was spot on and the car always felt planted.But I have to be honest and say I find the handling on my Altezza terrible. I back end swings around with small undulations in the road at relatively low speeds. So much so that I have no confidence in the back end when going around corners. Because of this I am not enjoying this car at all!!. The back seems to kick from side to side and I know that at higher speeds it would cause me to lose control.

Can someone advise me on a solution? I have just had 4 new bridestones fitted and the wheels laser aligned so tyre pressures cannot be the issue. I just had a major service which did not show up anything other than a hole in the exhaust and an acceleration flat spot.


Help Please!!

As you've just got new tyres (did ithey make any difference?) I'm not sure if my experience applies to your car. But for me very similar problems got cured by changing tyre brand. I went from Yokohama AVS dB550 to Continental Sport Contact 2 and it went from twitchy to wonderfully unperturbed. My guess is that it has to do with how soft and rounded the sidewalls are (the softer and rounder the better). Now I'm driving 18" Dunlop Sport Maxx and they're very good as well.

Please check the LOC knowledgebase for the proper wheel alignment data to compare with your alignment report. At least Hunter alignment equipment have had false data for the IS in their database.

It is the same, except for the axle stubs, which can be swapped over from the standard diff.

Its definately not the tyres as it was the same with the Yokohamas I had on before. Something to do with the susoension maybe?






Was also the same before wheel alignment

No dont think its lowered. Looks like standard springs and shocks

Mines the same nearly spun it coming down the on ramp on the m50 yesterday and i was going straight1 think the standard springs are just not very suitable for irish roads. getting some Tein springs for mine in the new year, that should help. Very jumpy at the rear. im the same came from FWD to RWD so it takes some getting used to to control the back end. A rear strut and uprated ARB's will get it stuck to the road

I beleve the IS200 Sport's LSD and the RS200's LSD are the same, both torsen items. They are typically very clunky, but then that goes for the whole driveline in these cars. They stand up to plenty of abuse though, and we have at least 2 1JZ conversions here in our Club of Altezzaness in Australia running through the standard LSD without any major drama's.

1 of our members will be fitting a TRD LSD shortly, and i shall get him to report here for those who are interested. We also had a member replace his standard LSD for a Cusco 1.5 way item as he was tracking his TTE IS200 alot. It was slightly more aggressive on take up but paid dividends on tight circuits.

With regards to your question re: RS200 suspension vs IS200 suspension. At least here in Australia and in New Zealand, the IS200's have a much longer suspension stroke and sit much higher than the standard RS200. Spring rates seem to be quite similar though, and for this driver at least, there's little difference in ride quality. Red Panda, i'd say that you need to look at the spring rate and shock rate of your existing setup, as there might be a mismatch. At the least, seek out a good suspension specialist before you go changing parts.

For those of you that are still interested.
The upper wishbone on the drivers rear was loose, causing the car to take on a prelude like, 4 wheel steer. Wishbone tightened and all is good again.... :)

Engine oil should be changed every 5k & (oil) filter every 10k...

Is the Oil filter easy to get to on the Altezza? It was a ***** to get out on the civic. Best filter, best oil to use???
