i have heard this setup is possible, is this true? on a 2gen

it requires a +40mm offset and some 2.5 springs...



what are the biggest tires u guys have on your 7's. and what exactly is offset. i think that would be pretty ****** cool to have like 1 foot long tires in back..

13BAce 01-31-2002 05:05 PM

I have 275/35/18's on an 18x9 with a +30 mm offset. The fenders need to be rolled for them to fit. With a +35 mm offset they would probably work without rolling.

aren't your tires a little tall, compared to stock diameter? i though u wanted to stay within 3% of the stock diameter so u don't lose torque, or throw off your speedo, did u have it recalibarted?



do u have any pics?

The tires are a little bit too tall, but they were only $75 each. :sigh: My speedometer is off by 2.8%. So when it says 100 I'm really going 102.8.

The convertible rims are great because they're so light.

1Revvin7 02-04-2002 04:19 PM

When you roll fenders you bend the inside lip upward so that the tire has a little extra clearance. My rims are 18x8 +30 mm front and 18x9 +30 mm rear.

Thanks treceb. It went across the river in November, but it should be able to make the trip again this month. https://www.nopistons.com/forums/pub...DIR#>/cool.png

OMG, nice car man. got any pics from behind? did u have the fenders rolled at a shop or did u do it yourself? how much did the tir+rim+suspension run you? what suspension do u have on that car again? it has to be a 2.5 or somthing?

Thanks. :smilewinkgrin: A friend rolled them, but they're not too pretty right now. I thought he had the fender rolling tool, but he just used a hammer and slide hammer. I'm going to get the car re-painted soon. So I'll get the rear fenders fixed up before then. I was going to use 89-91 bumpers and mouldings, but I still need the front bumper. I'm thinking about ordering that Bomex kit, but I'm not sure yet.



The rims were $215 each+$260 for the front tires+$150 for used rears. I have the Suspension Tehcniques springs(1" drop), Tokico Illuminas, Mazdatrix sway bar endlinks, and Mazdatrix front strut brace, nothing special.

1Revvin7 02-05-2002 03:13 PM

:wow: that is one of the best looking rear ends ever on a real car ( not on ******* show car with 1,000,000,000 into it ).

so how did u attain the +30mm offest on the front and rear?

im droolin over that setup man WOW, i can't wait

Thanks for the kind words. https://www.nopistons.com/forums/pub...O_DIR#>/11.gif I plan on doing some stuff to the body, but I'm not sure as to what I'm going to use. I'm either going to use 89-91 bumpers and mouldings or the Bomex kit.



I bought Konig Villains from http://www.discounttiredirect.com . The price was good, and I've always liked the way they look. You could get an HRE or Fikse in the same size/offset, but they'll be about

$8-900 each. The 18" Villains aren't that heavy for such a big rim.

1Revvin7 02-06-2002 11:00 AM

so how did u get the ******* offset? how much would it cost to get your fenders rolled professionally? wow those rims are expenive...

You just order the rim with that offset. It's not a special order or anything. I don't know how much it would cost to get done professionally, maybe $100-200?

Very nice looking car! Congrats

A cheap and easy way to roll your fenders is to hike the car up on a jack, and put a baseball bat of appropriate width between the tire and the fender. Lower the car back down and push it forward, the bat will roll from the back to the front. Then just lift the car again, pull the bat out, voila! One rolled fender. Using a hammer and a chisel sounds messy >=P

Yeah, the hammer method is painful to watch. https://www.nopistons.com/forums/pub...O_DIR#>/11.gif

Do you think that Bomex kits front bumper would look bad without the whole kit going on the car?

1Revvin7 02-06-2002 08:34 PM

what happens if your car hits a bump, or hits a bump when turning? BAM hits the fender?

I think it would look a little funny without the rest of the parts.

That's why the fenders get rolled.

1Revvin7 02-07-2002 11:46 AM

o on ur pic they look like 1/2 inch from the fender....

or are they totally inside the fender?

and i figure out that the offset is on the rim, but just for my own knowledge what is it? what is the difference between like 20+ and 40+ offset on a rim.

The pictures are from before the fenders got rolled. They're actually from before the car was even running. :wow:



Here's a great explanation of offsets: http://www.tirerack.com/wheels/tech/offset.htm . A +20 mm offset rim will "stick out" more than a +42.

treceb 02-07-2002 03:41 PM

hmm, so the higher the # the more it sticks out. And if you got a "-" offset, the tire/rim would stick inside the well, maybe hitting the body. coolz
