Hi All,

I recently purchased some F-Sport Parts (F-Sport Intake, Exhaust and Lowering Springs) for my 2008 IS250 Sports Luxury from Lexus of North Miami.

All the other parts were fine however, I have concerns regarding the lowering springs that they have supplied me (Part Number PTR07-30090), as I just don't believe they are the right ones for my vehicle. The Parts Manager at Lexus of North Miami had advised that the F-Sport Lower Springs they had supplied me is suitable for all IS and GS Models (even though the instructions indicate that it is for GS350 RWD only). I have searched through several other Lexus Dealer Sites (http://sewellparts.com) and the web and all list F-sport Springs Part Number PTR07-30090 suitable for GS 350 RWD model only and NOT IS models. I believe the appropriate part should be PTR08-53090 or PTR08-53080.

Lexus of North Miami have advised me that they have spoken to the Lexus F-Sport Division in Japan and that the part number they provided me for the F-Sport Lower Springs PTR07-3009 is the only one manufactured by the Lexus F-Sport Division now which is now suitable for all IS and GS Models and that it replaces part number PTR08-53090 or PTR08-53080 (which were the part number for the previous Springs for the IS models). The Parts Manager has also advised that he has sold several F-Sport spring sets to customers and they have successfully installed these springs on their IS250 with no issues at all. I'm currently trying to confirm the information that Lexus of North Miami has provided me with Lexus Headquarters to see if this is correct or if its a load of bull***** (as the dealership is just trying to clear it's stock).

Has anyone purchased and installed F-Sport Springs (Part Number PTR07-30090) on their IS250's? If so, was there any modification required and have you had any issues with the Spring set???

Thanks again and if anyone has any experience with this or if you could shed some light on the subject this would be very much appreciated!

Cheers

Mike

Although you can technically interchange the parts, you really shouldn't take the risk of that. But to answer your question, 53090 should be the correct part number. The GS f-sport springs have a different spring rate in comparison to the IS f-sports.

if i were you, i'd just go ahead and return the springs. it's not exactly what you wanted. lexus does interchange parts occasionally. for example one of my nuts fell off my knuckle so i had to order a new one. the new part is slightly different but works fine. but that should NOT be the case with springs. go ahead and return it, get your money back and purchase it from sewell. they'll get you the CORRECT part number at $218 + shipping. hope that helps!

I remember reading about something like that in med school.

Here's the link to my previous thread on the spring part #. If you have any questions, Gabrial Valle at Lex Tuners in CA (site vendor) really helped me out.
