No. I only had alignment after springs installed and it wasnt cover by the warranty

otakusan

I just bought a 2016 IS350 AWD in western Canada. Dealer said F-sport springs do not exist in Canada, but they are able to get them from Lexus USA. Now I'm wondering if they are just bringing in the RWD springs for me The springs haven't arrived yet, I wonder if I should shoot them a message and ask for a confirmation. But since they are installing it, and I have triple checked that no warranty is void... this will be a good test to see how these will do on an AWD car.

Answer

Wondering what the result will be as they are specifically stated not to be AWD compatible... Your warranty should not be affected as the are dealer option and installed.

i hope they'll check to see if they physically fit before ripping the suspension apart. Will post update when it happens.

Is front camber adjustable on these cars?

no, assuming you have OEM arms, the only thing that is adjustable is front and rear is toe.

Answer

Front camber is adjustable on the AWD version.

A poster a few above showed his tech adjusted the front camber after these springs were installed. as these springs are just a mild 1" drop, i see no reason to buy camber arms. so i'm puzzled as to why it needed an adjustment or how it was done. i'll have to look into that more. i'd like more negative for performance reasons (NOT stance reasons)

and... you sure the rear camber isn't adjustable? that's standard on just about all cars.

Answer

RWD: no camber adjustment.
AWD: front camber adjustment only.

That is, in stock form. Everything is adjustable with aftermarket parts.

With ~1" drop, no adjustment is required, it stays within specs.

Maybe I missed it, but how much do these go for at the dealer?

They're like $600 at dealer. get them on ebay for 1/3rd the price. Lots of local lexus dealers are eBay sellers.

But not compatible with AWD?

Sorry have no idea about awd

They physically fit the AWD, but no one has tried it and no one will know what the ride height will ending up being like and how the ride quality will differ... RWD cars have higher spring rates at back vs front, while the AWD cars have a more evenly split spring rate between front and back.

E46CT

That makes sense since a RWD car will have more weight in the back (relative to the front)

If they physically fit then the AWD car will be slightly soft in the front and slightly stiff in the back. I imagine any difference (assuming they fit) would be negligible and go largely if not completely unnoticed, particulalry if you aren't going for track times.
