Cheers Tony, did a few more miles in the ISF this weekend, had a trip to IKEA in Bristol joy of joys!
Anyway something is definitely not right, not only does the car want to go left all the time, at motorway speeds 70-80mph the car felt that it didn't want to go in a straight line. Best way i can describe the feeling is driving in a very strong crosswind however there was no wind outside of note. Car didn't feel confident at all.
Another thing I noticed was in the car park when doing a left turn the steering wheel wasn't too keen at finding centre again, it seemed fine when doing a right turn.
I definitely think this is something to do with the shock install, I cant hear anything loose or any knocking so I don't think its ball joints or track rods. I have been doing a bit of reading and apparently the top mounts need to be installed on the new shock in a particular way. I have read that there are arrows marked on the top mount that need to face in a particular direction? I have no idea which direction they should face but if incorrectly mounted it can affect caster settings.
I deffo need to get my caster readings done as a starting point, if they are out I will go back to the garage that installed them and get them to check but I cant find anywhere on the internet which direction the arrows on the top mounts should face for the Lexus ISF?
Have asked the question on one of the US forums so lets see if I get anything back. I'm guessing you cant see the arrows once the shock has been mounted? will have a look tomorrow from the engine bay. If I can, then my friend has the same car so can get him to check his otherwise it involves taking the strut off again.
Arrrgh!
