The Mekon

Sorry, but I don't do facebook, so those links are useless to me

Found one! In the past, I have looked many times for one on ebay, without success. Last night I checked the listings and there was one from a 2011 car for $125 and only 60km from where I live. Thanks for all the replies.

Does anyone know the price of a new engine undertray for an IS250. The one on my wife's car has split from hitting too many low kerbs. I don't want to go to a Lexus dealer and have a heart attack when they tell me it will be so many thousand dollars!

2010 IS250. No, did not change the front diff. I removed the front drive shaft and only use the Prado in RWD. It's great. Still capable off road as the rear diff is a LSD, the front is not.

Well done! Can you tell me what the previous ratio was? perhaps 10/41 and what is the ratio now. I recently changed my 1999 Prado over from 4.1 (10/41) to 3.72 (11/41) and love it. Had to change the tailshaft yoke as well. Speedo also reads 10% lower than previous, but only 6% lower than true. Wife has and IS250 and top gear seems about right - about 2400rpm at freeway speed (115kph). So you are saying the IS350 runs the same gearing?

Currently have a Is250 for my wife and I drive a beat up old 1999 Prado. Looking at scrapping the Prado (its that bad) and buying a Lexus RX350 2007-2010 model depending on what is around. But I want to take this car off road at times and may need traction beyond what the standard wheel/tyre combination offers. So what choices are there? I am thinking steel wheels from a RAV4 16x6.5 with 215/70 dual purpose tyres. Will the brakes fit inside these wheels? Has anyone here ever done a down size wheel conversion? Plenty of people wanting to do 19" and 20" wheels but I want the other way!

Just to update. At 61,000km the front discs were down to 25.7mm. Bought a set of DBA non slotted discs (kangaroo paw) and Bendix pads all up for $280. (makes the above post's $250 front pads seem a bit expensive) Fitted them and the dust is gone. Wheels stay reasonably clean, brakes are as good as ever.

Yes, you can borrow mine if you want, but I have no idea where you are! Bought mine on ebay for about $20. You do need the right tool. 64.5mm is the one. Suits many models of Toyota.

I agree with Atlantis Bought our IS 250 with 32,000 km. At this time I measured the front discs at 26.4mm. Measured recently at 46,000km and now 26.2mm Still within the factory wear limit (25 - 28mm)

Have a look at the Honda Euro (05-07) models. I bought a Lexus IS250 to replace a 05 manual Euro. Wanted an auto car for the wife who was always in the wrong gear driving the Honda. All I can say is the manual Euro is a much quicker car than the IS 250. The gearbox is an absolute gem for the person who wants to "drive" the car. Being 200kg lighter does help, the Lexus is definitely slow off the mark in comparison and the auto gearbox is changing down to 5th or even 4th when the Honda would roar up hills in 6th. that said I still think the 2010 IS250 we bought is a magnificent car.

This is a question I have asked myself. Why does the early (05-08) Prestige have same size 16" wheels front & back, but the Sports Luxury has the 17" with different rolling diameters? is there a suspension difference for the SL? I note the "new" model (2013 on) has 7.5" wheels as opposed to the older models 8". A sensible decision in my view, the tyres sit too far inside the rim on the older model. to me the best combination of wheels / tyres would be that fitted to the old GS300. 7.5 17" rims with 225/50 tyres all around. no need for the stupidly wide 245 rears.

What is so bad about a prestige is350? Wheels can easily be upgraded.

Sorry rakddon, not interested in your bigger brakes. The brakes are powerful enough as is for the 2.5 engine. What I want to know is what combination of pads/rotors will stop wear and dust.

Only had our 2010 prestige for a couple of months. Noted the huge amounts of dust the front brakes generate. Cleaning the wheels may become a full time job. While they were off I measured the discs and pads. Discs are down to 26.4mm (from 28.0mm) and pads around 6mm remains. This car has only done 35,000km, Is this wear and dust typical of all IS 250 from factory? What are the best rotors and pads to fit? I will be maintaining this car myself - no dealer repairs or service unless absolutely necessary.
