I am a huge Bilstein fan, but a quick search on their catalog reveals no stock type option for this car. I've been trying to read up on the F Sport shocks from Lexus are Bilstein. Are these available for an AWD 250 (2013)? Where are you guys getting these if so? Are they direct bolt in or other springs/mods required to run something like this.
Or, any other good brand (Koni, etc) options available out there that are just a bolt in, direct replacement option? Thanks guys.
There seem to be two versions of Koni kit for the IS. An older one with H&R springs, and the newer equipped with Eibach springs.
Eibach have the stock springs feel, while H&R provide more aggressive ride.
Koni Sport Kit with Eibach springs 1145-1031 (newer version). Front lowers approx. 35mm, rear lowers approx. 25mm
Koni Sport Kit with H&R springs 1140-1221 (older version). Front lowers approx. 35mm, rear lowers approx. 35mm
You might need to do more searching to see if the kit can be installed in AWD
KYB would be an option...they are widely know and used as replacements. Looks like they only make Koni for RWD.
A set of KYB for AWD is only $375 or so....https://ebay.to/2MSwOu4
KYB are also on Amazon with Prime too for same price or less but you have to piece together the set. The fronts take two different P/N due to the position of the brake line bracket. The rear is the same on both sides.
Front 55127 and 55126: https://amzn.to/2QJMmS9
Rear 551132: https://amzn.to/2FltZ0v
The problem these days with finding F-sport stuff for 2IS is that most dealers don't have access anymore since many have been discontinued.
Also, not sure if those Koni kits come with the top hats installed and ready to go. You may still have to get them compressed onto the shocks with an OEM hat. And for $1,000, might as well get some coilovers from Megan or BC.
