Those uprated front brakes appear to have been all that's been stopping me, as during its first M.O.T at the end of last month the local stealership discovered the sliders on the rear calipers were seized . The 3 year warranty had expired the day before, but brownie points to Lexus Cheltenham as they phoned Lexus GB and replaced both rear calipers under warranty. Apparently it's a common problem so may be a recall.
Needless to say the braking is now exceptional although I now get brake dust on the rear wheels again None on the front though, that ceramic based pad material is great.
Next on the agenda is a set of camber adjusters for the front, as despite the best efforts of Dr Bones we have inner tyre wear due to excessive camber. The Toyo T1-R's have still managed 22K miles, but they'll need changing before 24K.
The bad news is that no one has manufactured a camber kit for the second generation IS. TH Motorsports in the States have a design and are asking for a local 250/350 owner to volunteer their car as a donor car, but so far no one has taken the offer. I've queried Eibach in the UK but yet to receive an answer.
Try giving Megan Racing a call, they have things in development not posted on their website. I have their rear adjustable arms, good quality. http://www.meganracing.com/products/product_page.asp?catid=4
Good luck.
