Anyone else having the same experience?

Never had the R888R. But I have a set of Hankook Ventura RS4s that behave that way. They got really hard after a year. They would soften up and be ok hot days.
I put some Conti Sports on the car because itís my sons DD now.

Plus 315-35-17 tires are really hard to find anyway not to mention the price when you find some. I got these r888 for a deacent price as they where the last ones.

In this pic rears where still 275-40-17 but IIRC they lasted maybe three summers and they still had some thread in them? I do about 3kmiles/summer normally.

I haven't noticed that. There is not really anything else out there for 315/35-17 tires unless you buy the Nitto sister tire.

I tried running 275/40-17 tires but it was too easy to spin them.

Wow you guys have huge sizes compared to my tires!
I find with a good setup and weight balance (car on the scales to calibrate weight distribution) and something around 330/350hp itís enjoyable and good for a track day on those toyos .
For sure Iím the slowest but with this amount of hp it does not spin.
Also have ruf 17s

Iíve had made by an old motorsport builder a couple of brake cooling ducts, that helps a lot together with the black pagids at front I find a good compromise using those tires.
If available here in Europe Iíll try also some Hoosier in the future!

Slowly getting some time in on my Turbo, yes Paul, Rey.. I am working on it!

Removing the gauges to get at some nasty wiring from an old Hofco alarm system that was very well installed, I have no controls related to it and expect it to cause a problem at some point so decide to remove it.

Anyway, I've worked on any number of these cars and this is the first time I've run across a factory line to the boost gauge. Wonder if that was and Andial or AJR thing?




Typically, I've seen and an adapter/nipple with a rubber line and a hoes clamp.. I've also seen worse.

I remember those from ANDIAL setups way back in the '90s.

Andre,

I always thought the cooling air was coming out of the brake disk where you are attempting to force it in? Is there more to this design/setup than meets the eye? Or am I not visualizing your picture correctly?

These cooling ducts works on both sides of the disc.
They are an old 934 design, instead of taking the air from the front they work from under the car because I have the turbo s spoiler with no brake cooling holes.

They work very well, original ones were in fiber glass, these are aluminium.

This an old image of the homologation fiche.
