Hi All,

Long time member first time poster on the RX Forum.

Upgraded our GS430 (which was an awesome car..dont know if upgrade is the correct work) to a 2014 F Sport 350.

Its hard for me to leave things stock, but im thinking about adding spacers to give it a tougher stance. Anyone ran spacers?

Clutchless

Do a search. There is a big thread on this. I have the H&R 20mm spacers on my RX350 and think they improved the handling plus reduced body roll.

Same H&R 20mm spacer. (with original 235/55 R19)
But I think 20mm doesn't look too different from the original. (I only talk about the look, not function.)
25mm might be more aggressive, what do you think?

Clutchless

I have the 20mm spacers with 8 inch wide 19 inch wheels and 255/50/19 Goodyear Eagle Asymmetrical All Season Tires. The Goodyears are pretty wide for their size and stick out past the wheel which is great for curb protection, traction and a more aggressive look. They are great tires.

For those of you who installed the 20mm spacers, did you have to trim the stock studs at all? In looking at multiple sites where teh spacers are sold, I see notes where it "might be required" for the 20mm spacers, but is not referenced at all for the 25mm spacers.

I just got a 2010 RX450h which has Michelin 235-55/19's on it, and they are almost full tread, so wider tires are not in the picture for a while (though I will consider them in the future). Consequently, I'm thinking about going with 25mm spacers, but don;t know if that will be too wide if/when I go to the 255's at a later date.

Opinions? Insights?

Thanks,
Pete

Get the H&R Trak Plus, it is a simple bolt on over your old studs. DRM type spacer 20mm is part no. 4065600, 25 mm is part no 5065600.
The Reference to Lexus RX 335 is just a typo, (maybe due to German translation or Europe models) it is for the RX 350 or 450h.

Look at this link and I highly recommend you find the old thread.

I think 20 mm is plenty wide enough if going to wider wheels and tires like I did. See my photos above.

F250

Thanks. Just to confirm, then... you did NOT have to trim the stock studs for the 20mm spacers, correct?

I'm not changing wheels, but will probably do the wider tires on the existing wheels when these tires are ready to be replaced..

Clutchless

Correct. I DID NOT HAVE TO TRIM THE STOCK WHEEL STUDS. They bolt on right over them and fit perfectly. H&R is a highly regarded German manufacturer. These spacers are made in Germany. They are very well made. It is very easy to install them. I do recommend you have a torque wrench to make sure everything is at the proper 76 (I do 80) foot pounds torque. Then check the wheel torque again ( not the spacers ) after 100 miles.
Also put some antiseize on the backs of the spacers so they are easier to remove if you need to do so later on.

F250

Thanks for the confirmation, and for that reminder. Oh, yes... I learned that particular lesson thoroughly when I replaced my rear rotors on my 2002 F250 after they had been on the truck for 120K miles. On those wheel systems, because of the heat they can receive from heavily used brakes, I typically spread a thin film of the ultra high temp rated Permatex Ceramic brake lubricant between any metal surfaces which can corrode or get stuck together. It has worked like a charm, and beats the devil out of having to swing a 2-lb short handle sledge hammer for an hour or so to knock the parts loose.

The vendor marketplace forum has an H&R spacers vendor offering discounts to CL members.

F250

Thanks for that tip, Clutchless. I just posted up my RFQ for them.

F250

The vendor had to do some searching, and found, as we already know based on Clutchless' input, that they are listed as being a fit for the RX330.

Clutchless

Actually it is the rare Lexus RX 335.

F250

I know that's what the Trak+ website shows, Cluthless, but the vendor says HIS list shows them for the RX330... and I verified that his part number for the H&R spacers matches exactly with what you posted above. This is yet one more point of potential confusion fur us buyers to have to sort through. Seems like the cross references lists may have been tweaked, but are still not in sync and not completely up-to-date. That's why I posted what the vendor told me... so anyone else who runs across this issue can have some additional details to sort it out.

Really, though, as long as we refer to the wheel bolt pattern and bolt thread pitch ( 5:114.3 pattern, 60.1 center bore, 12 x 1.5 studs ), it shouldn't matter which vehicle the vendor lists shows for the spacers.

Clutchless

I agree and we know that DRM type spacer 20mm, part no. 4065600 fits the RX 350 because that is what I and a few other members have installed.
There was no reason for Toyota/Lexus to change the hub size, bore or bolt pattern or stud length on the new model. To save manufacturing costs that size is common across many Toyota/Lexus vehicles as are wheel offsets which may vary only a few mm.
