I need a set of spacers to use 14" wheels. Is it safe to use 5mm spacers without using extended wheel bolts ? I´m thinking of buying a set of H&R spacers , and they come supplied with the bolts , however they are a bit of a PITA to fit and I don´t need the extra length for the 15" wheels I normally use.
Car is an 89 CRX by the way.

 

You should be fine

 

If im not mistaken, the HC or SCCA rule book says its ok as long as the nut threads on the stud the same distance as the diameter of the stud itself.... or something like that.

 

That´s good to hear. I did a search on wheel spacers , and someone suggested that it wasn´t neccessary to use spacers in the rear even if you used them up front. Is this true , and what is the logic behind it (I´d guess that you should keep offset changes the same for front and rear) ?

 

Usualy the wider the stance the more cornering stability you have. Since front wheel drive cars tend to under steer that setup might be usefull. Try it for a while with the front and than with all four and see which way gives your car better ballance.

Depends on the offset and clearance of your wheels whether you need them or not.

Yeah , I understand that. My concern was if it was a good idea to change offset on only one end of the car. I know they will fit fine as is in the rear. The wheels are 14x6 ET45.
Plan on using these for R tires for track driving.

really? never read this one, maybe i missed it. but the diameter of the bolt is like 10-12mm anyway. youd barely meet this requirement and id be rather wary with half my nut holding on to the stud. i would think a full use of the threads would be necessary. which you cant get without longer studs.

i think some japanese magazines show some setups of using wider tires/wheels up front than the rear. maybe thats where the thought of using a wider offset up front comes from. buy all 4 and try it out... maybe theres a noticable difference.

I've heard the same thing. I think I also heard that from Tirerack. I think it comes out to a minimum of 5 full turns of the nut.

 

I've heard it stated as a minimum of six full turns of the lug nut...

 

at the shop i work at, it needs 5 full turns to be ok. has any one here ever used ET lug nuts?? i think it stands for Extra Turn or Extended Turns or something. we use those at my shop some times. they are shaped differentlly than normal lugs so you get more turns. ???

 

just fyi, i checked the number of threads on the stock lug nuts and its 10 even. if 5 is fine, its exactly half of normal.
