Is this possible? What are the differences between the Prokits for the 250 and the 350? I am under the impression that the springs are identical except when you use the prokit for the 250 on a 350, there is a bigger drop than if you used the 350 kit on a 350.

Is this correct? Are there any drawbacks to using the 250 kit on a 350? Does it really drop the car more if you use a 250 kit on a 350 compared to using a 350 kit on a 350?

Thank you

You should do a search. This has been posted a million times. The answer though is yes they are compatible and the 250 lower your car more. Just look at eibachs specs and you can see for yourself.

who cares about eibach though, Hotchkis is where its at. They even come with new bump stops and have better specs on their drop. The eibachs for the 250 leave your *** end high. The 350 springs dont lower it enough. H&R is a good drop, but a tad low for some.

Which hotchkis springs would you recommend? And also, which H&R springs would you recommend? I'm going to be running g-spider wheels with spacers. I want the wheel well to sit right on top of the tire with maybe a 1 finger gap but I want to retain the Lexus ride quality.

Only one type of both Hotchkis and H&R springs I believe. I've heard great things about both brands though not too many people on here have them on their personal IS. Wouldn't hurt to try.

I know everyone has their own personal taste on how it should look but the difference between the front and rear is greater on the hotchkis then on the eibach 250. So why complain that the eibach make the rear end took too high?

Front drop on the hotchkis is 1.625in rear is .875in: difference of .75in
Front drop on the eibach is 1.4in rear is 1in: difference of .4in

Good point!

No it doesnt. Ask me how I know.

sincityIS

that is a good point, but when I saw them on a car at SEMA they car had 235/35/19 up front and 275/30/19 in the rear. I know the rear tires are a smidge smaller diameter than the front and the car still looked to be pretty level, approx. 1/8 inch more gap in the rear than the front. In any event I have used a lot of hotchkis stuff in the past and the quality has never let me down.
Especially since he is going to be running the stock wheels where the rear tire has a lot more meat on it. This setup will provide for a perfect wheel gap at all 4 corners with the stock tire sizes.

Extreme you are going to want to get some wheel spacers as well because if you lower it the wheels will appear to be sucked in. Get some 20mm H&R spacers to put on there and your car will look great.

Thank you sincity. I am aware of that and am looking into either getting spacers or changing my wheel choice.

I think he meant Eibachs made for the 250 installed on a 350...
