So I have a 2014 Lexus is250, and I’ve been looking for RSR downs (T195D) for the longest time, since every place seems to be out of stock, and recently I just found out that the Lexus GS450h down springs had the same exact part number (T195D). I was wondering if I order the GS springs instead, will they work on my IS as intended? I’m a little new to this, so I don’t know how strict part numbers are across certain car platforms

 

So recently I ordered RSR superdowns for my 2014 is250 and sadly am not able to run them. The front is perfect and has about a 1” gap from the fender, but for the rear, my tires rub my fenders because of my aggressive tire setup (I went too wide with my tires). I’m now trying to get a hold of some RSR downs (T195D) to throw on the rear, but every place is out of stock. My question is, what are some good alternative springs that will give me the same exact drop on the rear as the RSR downs?

 

I believe I saw "ARK" springs which give a better drop than RSR Downs, wish I saw those initially but I think RSR has been making suspension parts for Lexus longer. ARK I know makes a nice sounding exhaust for the IS. This is a good idea because the RSR Down drop for the front is def not enough, it bothers me a bit that the front of the car looks higher.

Can you post a pic of the front of your car? Are you AWD? What tires are you running & wheel spec?

 

i bought rsr down springs about a month and a half ago when they were still in stock by various vendors. i just did a search and it appears that some do have it in stock, although i dunno if they are accurately reflecting their inventory. you can certainly find new rsr springs on ebay, though.

 

Welcome!

To me it looks like the GS 450h has a part with the SKU T175D, not T195D.
