Hello all. I have always liked the 993...and today found a 1995 C2Cab up here in AK. I bought a Cay S a year ago because it was more practical here....but still yearned for a 993. Will finalize the deal on Monday and very excited to have this car for those long summer days. My first (of many I am sure) question is:

It has stock/chrome 17' wheels which are not in great shape and my GF says she will buy me new set. I would like 18"...any problems on this car? It is fully stock. I have searched the forum on this but still not clear. Will 18"x8 with 225-40ZR18 front and 18"x10 with 285-30ZR18 rear work...any rec's will be great!!!I will post pic's this week.

Thanks...sorry about the new question....I am starting the 993 learning curve...AK

 

Greetings and congrats on the 993. I can't answer your wheel question, but you will certainly get an answer here at Rennlist.

 

Welcome. Be sure to peruse the archives and the FAQ at the top of this forum. There is a steering rack brace recommended for 1995s running 18s. 285s worked fine on my former 97 car, but it was normal (SUV) US ride height.

Good luck!

 

I agree with Chris. You need the steering rack brace ( a $40 item) to mount 18's as per factory recomendations. I have 285's on my racecar without problems but I have a lot of negative there. A more appropriate size for you would be 265 in the rear and you will not have any problems.

Oh and if for some very bizarre reason you even plan on treking down to Seward please let me know!

 

Thanks guys......AK

 

Welcome to the 993 world! Another to consider is the fact that the 18's can be damaged easier by potholes... not that you would have any potholes up there.

 

hello and welcome

I am not exactly sure how the roads are where you will be driving the car, but knowing the road conditions in areas of northern Canada, I would guess you have your share of pot-holes, expansion cracks and frost heaves too!!

Considering that, and the fact that it is a cab, maybe you should consider a nice set of 17s ??

When I was test driving cars in Toronto (not northern Canada, but a lot of rough side streets ) I could always tell if the car had 17s or 18s. They all had stock suspensions and low mileage, so I assume that most of the difference was the extra sidewall on the 17s.

Don't forget to post some pictures!!

Follow the factory info. This is in the factory tech bulletins.

Front: 225/40X18 wheels 8X18, 52mm offset
Rear: 265/35X18 wheels 10X18 65 mm offset

Curious: what does your owner's manual say? Did you read it?

 

He probably doesn't have the manual yet as he hasn't purchased the car. I would disagree with others, I have 285's on my lowered (H&R springs- they suck with stock shocks, lemme tell ya) 993 and they don't rub in any situation I have encountered in 8 months or so. I honestly can't remember how much negative camber I have, but it isn't a whole lot. The problem is, it seems every car is different. Some people rub, and some do not.

 

Ray, as he doesn't have the car yet, he may have not read the manual yet.
I know i didn't read my manual before i had it

Cayenne Alaska, if you do a search on running 285s on standard body 993s, you will find some info. IIRC, if you stick to exactly the factory offset on a 10 inch wheel you should be able to use the 285s without rubbing. Ray listed the offset in his post above.

This setup is optimal IMO of course.

Minimizes oversteer to some extent. If you go for bigger rears... then you are back to sq 1...

 

Hi --

The manual for '95's does not have any mention of 18" wheels (just the factory 17" cup wheels).

But, the above mentioned off-sets are correct.

Here is a pic of my '95, with factory 18" wheels, 285/30's on the rear.

Standard suspension, no rub issues. Best of luck in the great north!

 

Welcome and ditto on the 265/225, that's what I have fitted. And I think Monique means "understeer" in the post above. Wider rears will (should) give more grip in the back and further reinforce the understeer that the factory has built in the stock set-up. Is the car on stock supsension?

Enjoy

Nol

 

I like it Jeff A!!! Right, no manual yet...should finalize deal tomorrow and I can actually start learning more...just getting a head start as I can't contain myself and taking opportunity of the offer for new wheels. This info is VERY helpful...yes..lots of potholes..with 50K miles on it.....will let you know if I play it safe (265 rear) or go for it (285)...or repair the stock 17"...I love all these new decisions I have to make!!

Here is a pic of the car 2 years ago with the soon to be previous owner (smudged out). It needs some TLC now. AK
