Penport

This happened to me a few weeks ago - only once though - after a very heavy storm the night before. I put it down to damp in the circuitry as the problem resolved itself once the car warmed up - hasn't happened since.

I too have had similar problems with various front suspension components replaced under warranty at both my services so far. I'm now 6k after the last service and the noises are beginning to come back ....

37 all round with reduced outer tyre wear and increased mpg - again as advised by the excellent Dr Bones

Following several trips to the "doctor" I now run 37 front 35 rear on my SX. I was getting excessive outer wear on my front tyres which so far seems to have been cured by full geometry check (recommended ++) and this pressure combination. however as you say there are lots of opinions on the subject  :winky:

will it make any difference with yours being a Sportscross??

←

Would have thought not - only slightly more weight over the rear - which makes for even better handling :winky:

Well done a bit of searching through the forum..

There seems to be no concensus regarding tyre pressures.

Looked at both the maual and the door piller sticker.  Door piller advised 3 Bar, which I thought was a bit excessive, so I went got 2.6 f / 2.7 r (about 38 psi)

What do most stick in their IS300..

I have about 1000 miles or so to do in the next week and a bit, so didnt want to get it too wrong :)

Yep - Tony's the main man - he worked his magic on my baby as well

Took my Sportcross down to Watford today - and what a difference! Now that the geometry and wheel alignment has been sorted by a real enthusiast the car feels MUCH better. Tony took the best part of 2 hours to expertly get the right balance of geometry to both improve handling and reduce uneven tyre wear.

At my last service (9K miles ago) the dealer put on new front tyres and did a "full geometry". Yet there's already inner wear on both tyres. This has been sorted today so hopefully I'll get a decent life out of these tyres - so recouping the cost (and then some).

The big difference has come in the handling - the car "sits down" much better under acceleration and really flies round corners - sooooooooo much more fun - had a smile on my face all the way home :D

If you live anywhere near Watford or are just passing I'd recommend a visit.

Also with pwr on with the Autobox,it should be Keener to downshift under part throttle.

Cheers chips.

Those two buttons are only available on the auto box ............

Just make sure you hit the right one. When I first got my car I hit the wrong one when attempting a quick entry onto a dual carriageway - very embarassing

Thanks - nice to know that my car setup is "normal"

My SX came with 215 front and 225 rear and the manual implies that's the correct combination.

So should I change to the same size, and will it improve the handling?

←

NO!... if your SX came with 215 front and 225 rear, We need to find out why before any advice is given, can you show the exact wording from the manual.

The manual says (page 273 onwards):

Specifications (IS300) Tires and wheels (Type A) front 215/45ZR17 rear 225/45ZR17 (TypeB) 215/45ZR17 (Sedan:Type C) 205/55 R16 89V (Sportcross:Type C) 205/55 R16 89V

It then goes on (helpfully) to suggest that rotation of 215/225 combination is not a good idea. BTW my car is MY2002.

Yeah - different front/rear - a bit of a pain when you're used to rotating tyres - so it's not always possible to have the most grip at the rear. At least I know my traction control works Ok

Thanks - can't do that on a Sportcross - fronts are 215/45/17, rear 225/45/17

The rear tyres on my Sportcross are in need of replacement - after some research on this site I've decided to get some P Zeros. But what will be the result of then having Bridgestone Potenzas on the front and P Zeros on the rear?

I hope it won't be a problem but am looking for an expert opinion.

The fronts were changed at the last service (8K miles ago) and having more grip on the front totally screwed the handling so I'm looking forward to redressing the balance. My plan is to replace the fronts with P Zeros when worn (although nearside is already showing neven wear on outer edge.

My Sportcross was doing exactly the same - luckily it was due a service last week - ECU reprogrammed - now starts perfectly every time :D

I recently had my front tyres (Bridgestones) replaced at Lexus Leicester. After a bit of haggling I paid £100 + VAT per corner fitted.

I've been enjoying my IS300 SC for 3 months now and am well pleased with it in every way except for one:

An annoying groan/clonking noise that's coming from the rear of the car. It's only occasionally there, sometimes on cornering, sometimes accelerating or braking. To be honest in any other car I'd probably just put up with it, but the quality of the rest of the car kinda raises your expectations.

Any ideas? Could it just be the extra bulk of the "estate" flexing??

And before anyone asks - no there's nothing moving around in the boot

With most automatics you need to check the level with the engine running at noraml operating temperature - just mind your fingers

i understand that the mute wire is yellow (from previous threads) so I'll find out when I take it out.

Thanks for the welcome.

I had a good search on the topic last night and found lots of very useful info.

I'll contact Dashmount

Hello everyone

Today I bought a 2002 IS300 Sportcross that I absolutely delighted with :D - what a car! A huge step up in class from my modded Saab 9-3.

Anyway I'd like to fit my Motorola V50 car kit into the Lexus and am looking for some help. I'm not at all bothered about it linking in with the radio (dealer advised that this often "messes up the electrics"). Can anyone tell me where to take a feed from - my guess would be somewhere behind the glovebox? And are there any mounting brackets available for the IS?

Thanks in advance
